Charles Ellicott Commentary Psalms 36:8

"They shall be abundantly satisfied with the fatness of thy house; And thou wilt make them drink of the river of thy pleasures." — Psalms 36:8 (ASV)

They shall be abundantly satisfied. —Better, to preserve the parallelism, literally, They shall drink to the full. The Septuagint and Vulgate render it, “They shall be intoxicated with,” etc.

Fatness, therefore, is not here the fat of the sacrificial offerings, but the stream of grace flowing from above, to enrich people as the rain enriches the earth. (Compare to Psalms 65:11, where “fatness” means “fertilizing showers”)

The house of God may either be the whole earth (Gesenius), or, more probably, heaven, just as the temple is used (Psalms 11:4; Psalms 18:6; Psalms 29:9). God’s loving-kindness is regarded as

“An endless fountain of immortal drink,
Pouring to us from the heaven’s brink.”
