Psalm 136:20 and Deut 7:9 connection?
How does Psalm 136:20 connect with God's promises in Deuteronomy 7:9?

Setting the Scene

Psalm 136 is a responsive hymn celebrating specific acts of God’s “loving devotion.”

• Verse 20 highlights one such act: His defeat of “Og king of Bashan—His loving devotion endures forever.”

Deuteronomy 7:9 establishes the theological foundation: “the faithful God who keeps His covenant of loving devotion for a thousand generations with those who love Him and keep His commandments.”


Key Term: “Loving Devotion” (Hebrew ḥesed)

• Same word in both texts—linking a timeless promise (Deuteronomy 7:9) with a concrete historical event (Psalm 136:20).

• ḥesed is covenant love: active, loyal, guaranteed by God’s character rather than Israel’s performance (cf. Exodus 34:6; Lamentations 3:22-23).


Historical Backdrop: Og, King of Bashan

Numbers 21:33-35 and Deuteronomy 3:1-11 record Og’s defeat east of the Jordan.

• Og’s territory later allotted to the half-tribe of Manasseh (Joshua 13:12-13).

• To Israel, Og represented an impossible obstacle; to God, he was another opportunity to display covenant faithfulness.


Promise Announced → Promise Kept

Deuteronomy 7:9:

1. God is faithful.

2. He keeps covenant ḥesed.

3. He does so “for a thousand generations.”

Psalm 136:20 (and surrounding verses 17-22) shows that:

1. God struck down specific kings (Sihon, Og).

2. He “gave their land as an inheritance… a heritage to His servant Israel” (vv. 21-22).

3. Every line ends, “His loving devotion endures forever”—the lived-out proof of Deuteronomy 7:9.


Connecting Threads

• Promise of Land: Genesis 15:18; Deuteronomy 34:4. Og’s defeat moved the promise toward fulfillment.

• Covenant Continuity: God’s actions in the conquest echo earlier deliverance (e.g., Red Sea, Psalm 136:13-15), reinforcing that His ḥesed is consistent across generations.

• Faithfulness Despite Time: Roughly forty years separate Deuteronomy 7:9 (spoken on the plains of Moab) and the Psalmist’s later reflection—yet the refrain remains unchanged.


Practical Takeaways

• Historical victories like Og’s defeat are not isolated tales; they are case studies in covenant reliability.

• What God pledges, He performs—whether in ancient battles or today’s personal challenges (cf. 1 Thessalonians 5:24).

• Remembering specific past mercies fuels present trust; recount God’s deeds as Psalm 136 does.


Summary Snapshot

Deuteronomy 7:9 declares God’s unbreakable covenant love; Psalm 136:20 showcases that love in action. Og’s downfall stands as a tangible, historical witness proving that the Lord’s “loving devotion endures forever.”
