Albert Barnes Commentary Psalms 145:19

"He will fulfil the desire of them that fear him; He also will hear their cry and will save them." — Psalms 145:19 (ASV)

He will fulfil the desire of those who fear him—Of those who worship him with reverence—those who are his true friends. See the notes at Matthew 7:7-8; notes at John 14:13; notes at 1 John 5:14; notes at Psalm 34:15.

He also will hear their cry, and will save them—He will regard their expressed desire—their earnest prayer.
