Deuteronomy 9:5 explains why it's not because of Israel's righteousness — the immediate reason for the caution in verse 4.

In Deuteronomy 9:6, immediately following, it repeats that possession is not due to righteousness because Israel is stubborn — reinforcing the same point.

Deuteronomy 7:7 reinforces the same point: God chose Israel not for their size or merit, but by His own love.

In Deuteronomy 7:8, the positive reason is given: God’s love and oath, not Israel’s righteousness. Both verses deny human merit as the basis for God’s action.

Deuteronomy 8:17 similarly warns against claiming personal power for wealth—both caution against attributing blessings to one’s own righteousness or ability.

In Deuteronomy 18:12, the same phrase 'because of these abominations the LORD drives them out' directly reinforces Deut 9:4's reason.

In Deuteronomy 7:1, God clears away the seven nations — providing the list of nations driven out, as Deut 9:4 assumes.

In Deuteronomy 12:31, the nations' child sacrifice exemplifies the wickedness that caused their expulsion in Deut 9:4.

In Titus 3:3-5, salvation is not by our righteous works but by mercy — echoing the same principle that blessing is not earned.

In Genesis 15:16, the Amorites' iniquity not yet full explains the delay — same principle of wickedness determining dispossession.

In 2 Timothy 1:9, salvation is not by works but by God's purpose — mirroring Deut 9:4's denial of righteousness as the reason for possession.

Ephesians 2:5 declares salvation by grace, not works—directly echoes Deuteronomy’s theme that God’s favor is not granted because of human righteousness.

1 Corinthians 4:7 asks why boast as if you did not receive—directly challenges boasting in anything as if it were earned, just as Deuteronomy denies personal righteousness.

Romans 11:20 warns against pride and reminds that standing comes through faith—mirroring the warning in Deuteronomy not to boast in one’s own righteousness.

Romans 11:6 insists grace excludes works—directly parallels the principle that salvation or blessing cannot be earned by human righteousness.

Ezekiel 36:32 repeats that God does not act for Israel’s sake and calls for shame—reinforcing that human merit is not the basis for God’s deeds.

Ezekiel 36:22 states God acts for His holy name, not for Israel’s sake—echoing the same denial of human righteousness as the cause of divine favor.

In Exodus 34:11, God promises to drive out the nations — this is the original pledge that Deut 9:4 references as fulfilled.

In Leviticus 18:25, the land itself vomits out its inhabitants due to iniquity — personifying the judgment Deut 9:4 describes.

In Leviticus 18:24, the nations' uncleanness from their practices is why God drives them out — specifying the nature of their wickedness.

1 Corinthians 4:4 says a clear conscience does not justify—like Deuteronomy, it undermines relying on self-assessment of righteousness before God.

In Judges 11:24, Jephthah's argument that each nation possesses what its god gives parallels the logic that Israel's possession is from God, not their own righteousness.
