Echoes: Where the New Testament Reuses the Words of the Old
An echo is when a Bible writer reuses the words of an earlier passage. Sometimes it is a full quotation, sometimes just a phrase, so that readers who know the first story hear it again in the second.
The Echo Finder listens for them by computer. It compares every New Testament verse with every Old Testament verse and scores runs of shared, uncommon words that sit close together. A computer can measure how loud an echo is. Only a reader can decide whether it was meant, so every echo shows its evidence, and you can test it yourself.
The father ran
Genesis 33:4: Esau, however, ran to him and embraced him, threw his arms around his neck, and kissed him. And they both wept.
Luke 15:20: So he got up and went to his father. But while he was still in the distance, his father saw him and was filled with compassion. He ran to his son, embraced him, and kissed him.
The prodigal's father runs to his son, embraces him and kisses him. Genesis has the same three moves when Esau runs to meet Jacob, the brother who had cheated him, and the two are reconciled. Jesus' hearers knew that story: a wronged man running to embrace the one who wronged him. That is what the Father is like.
Honest note: On shared words alone, the computer ranks Genesis 29:13 (Laban runs, embraces and kisses Jacob) slightly higher. Genesis 33:4 fits the parable better because it is a reconciliation, and both verses add the embrace at the neck in the older translations. Commentators such as John Gill connect the two.
“Nothing unclean has ever entered my mouth”
Ezekiel 4:14: “Ah, Lord GOD,” I said, I have never defiled myself. From my youth until now I have not eaten anything found dead or mauled by wild beasts. No unclean meat has ever entered my mouth.”
Acts 11:8: ‘No, Lord, I said, ‘for nothing impure or unclean has ever entered my mouth.
When God tells Peter in a vision to eat unclean animals, Peter protests, “No, Lord!” Centuries earlier, when God told Ezekiel to bake his bread over dung, Ezekiel protested in almost the same words: “Ah, Lord GOD! I have never defiled myself… No unclean meat has ever entered my mouth.” Both are faithful men asked to cross a line, and in both God answers: He gives Ezekiel a concession (Ezekiel 4:15), and He tells Peter, “Do not call anything impure that God has made clean” (Acts 10:15).
Honest note: The situations differ. Ezekiel's sign was about Israel eating defiled food in exile; Peter's vision is about welcoming Gentiles. The wording is close enough that older commentators such as Adam Clarke called the resemblance remarkable.
“Besides women and children”
Exodus 12:37: The Israelites journeyed from Rameses to Succoth with about 600,000 men on foot, besides women and children.
Matthew 14:21: About five thousand men were fed, besides women and children.
Matthew counts the crowd Jesus fed the way Exodus counts Israel leaving Egypt: the men, “besides women and children.” The scene fits: a multitude, a desolate place (Matthew 14:15), and bread from God's hand, just as in the wilderness after the exodus.
Honest note: Ancient counts often listed only men, so the phrase alone proves little. What makes the echo likely is the setting, bread for a multitude in the wilderness, which is the exodus story. Working Preacher (Luther Seminary) reads Matthew's feeding this way.
Birds nesting in its branches
Ezekiel 17:23: I will plant it on the mountain heights of Israel so that it will bear branches; it will yield fruit and become a majestic cedar. Birds of every kind will nest under it, taking shelter in the shade of its branches.
Mark 4:32: But after it is planted, it grows to be the largest of all garden plants and puts forth great branches, so that the birds of the air nest in its shade.
Jesus' mustard plant grows until “the birds of the air nest in its shade.” Ezekiel used that picture for the kingdom God Himself would plant: a cedar where birds of every kind nest in the shade of its branches. Daniel used it for Nebuchadnezzar's great empire. Jesus gives the picture of a world empire to the kingdom of God, which starts as the smallest seed.
Honest note: The link to the Old Testament tree is widely accepted. Whether the birds stand for the Gentile nations is debated.
The earth opened its mouth
Numbers 16:32: and the earth opened its mouth and swallowed them and their households—all Korah’s men and all their possessions.
Revelation 12:16: But the earth helped the woman and opened its mouth to swallow up the river that the dragon had poured from his mouth.
In Revelation the earth opens its mouth to swallow the flood the dragon pours out after the woman. Those words describe the ground swallowing Korah's rebellion in the wilderness, and Moses' song says of Pharaoh's army, “the earth swallowed them up.” Revelation 12 is full of the exodus: the woman is carried into the wilderness on “two wings of a great eagle” (12:14), just as God carried Israel “on eagles' wings” (Exodus 19:4).
Honest note: Revelation usually draws on several passages at once, so it is better to hear a family of echoes here than to pick one source.
Like the roar of many waters
Ezekiel 1:24: When the creatures moved, I heard the sound of their wings like the roar of many waters, like the voice of the Almighty, like the tumult of an army. When they stood still, they lowered their wings.
Revelation 14:2: And I heard a sound from heaven like the roar of many waters and the loud rumbling of thunder. And the sound I heard was like harpists strumming their harps.
John hears a sound from heaven “like the roar of many waters.” Ezekiel heard it by the River Kebar: the wings of the living creatures “like the roar of many waters, like the voice of the Almighty.” In Ezekiel 43:2 it is the voice of the God of Israel Himself. And in Revelation 1:15, it is the voice of the risen Jesus.
Honest note: The computer picks up the phrase in Revelation 14:2; Revelation 1:15 applies the same sound of God's own voice to Jesus.
Five loaves: test it yourself
1 Samuel 21:3: Now then, what do you have on hand? Give me five loaves of bread, or whatever can be found.”
Matthew 14:17: We have here only five loaves of bread and two fish, they answered.
The computer flagged this one, and it isn't in the cross-reference list we check against. The disciples have “five loaves of bread.” David, running for his life, asked the priest for “five loaves of bread.” Run the tests: the words match exactly (volume). Matthew's readers knew the David story (availability). Jesus Himself brings up this very episode when His disciples are hungry (Matthew 12:3–4), so it was on His mind (recurrence). And Matthew presents Jesus as the Son of David (thematic coherence).
Honest note: We have not found this connection in the commentaries we checked, and five loaves may simply be what a boy or a priest happened to have. Weigh it yourself; that is what the tests are for.
Test an echo yourself
Richard B. Hays (Echoes of Scripture in the Letters of Paul, 1989) gave seven tests: availability, volume, recurrence, thematic coherence, historical plausibility, history of interpretation, and satisfaction.
