Albert Barnes Commentary Psalms 37:19

"They shall not be put to shame in the time of evil; And in the days of famine they shall be satisfied." — Psalms 37:19 (ASV)

They shall not be ashamed in the evil time - In times of calamity and trouble. The word “ashamed” here refers to disappointment; as when one goes to a fountain or stream for water and finds it dried up. See Job 6:20 and Psalms 25:2-3. The idea here is, that when times of trouble and calamity come, in seasons of famine or want, they will find their expectations, arising from confidence in God, fully met. Their wants will be supplied, and they will find him to be their friend.

And in the days of famine they shall be satisfied - Their needs shall be supplied. God will provide for them. See Psalms 37:25. This is in accordance with the general promises which are made in the Scriptures, that God will provide for the needs of those who trust in Him. See Psalms 37:3.
