Again the psalmist reminded the reader of God's remembering His unique promise to Abraham (cf. v. 8). The Lord brought Abraham's descendents into the Promised Land and dispossessed the Canaanite tribes. He even gave them food that the Canaanites had planted and cultivated. He did all this so the Israelites would obey His will for them and experience all the good things He had in store for them. The psalm closes with a final call to praise the Lord ("hallelujah").
A key word in this psalm is "remember"(vv. 5, 8, 42). By remembering how faithful God had been in remembering His promise to their patriarch, the Israelites would remember to praise Him. God's people profit from reviewing history because it reminds us of God's faithfulness. This reminder encourages us to trust His promises to us. We see that He has been consistently faithful to His word throughout history.
