Albert Barnes Commentary Psalms 145:8

"Jehovah is gracious, and merciful; Slow to anger, and of great lovingkindness." — Psalms 145:8 (ASV)

The Lord is gracious - See Psalm 86:5, note; Psalms 86:15, note.

And full of compassion - Kind; compassionate; ready to do good. See the notes at Psalm 103:8.

Slow to anger - See Psalm 103:8, where the same expression occurs.

And of great mercy - Margin, great in mercy. His greatness is shown in his mercy; and the manifestation of that mercy is great: great, as on a large scale; great, as manifested toward great sinners; great, in the sacrifice made that it may be displayed; great, in the completeness with which sin is pardoned—pardoned so as to be remembered no more.
