Numbers 21:14 quotes the Book of the Wars of the Lord — both are poetic citations from ancient records, linking two old songs.

Numbers 32:37 records the Reubenites building Heshbon — directly fulfilling the call 'let it be built' in this ballad.

Isaiah 14:4 introduces a taunt against Babylon, mirroring the ballad singers' opening here — same literary form of a mocking proverb.

Habakkuk 2:6 also begins a taunt with 'take up a taunt', echoing the ballad's opening — a common prophetic pattern.

Jeremiah 48:4 mourns Moab's destruction — the same Heshbon built up in this ballad is now laid waste, a dramatic reversal.
