'Relieve' in the Bible

He came to the sheep pens by the way, where there was a cave; and Saul went in to relieve himself. Now David and his men were abiding in the innermost parts of the cave.

but I would strengthen you with my mouth. The solace of my lips would relieve you.

Hear my prayer, Yahweh. Listen to my petitions. In your faithfulness and righteousness, relieve me.

Learn to do well. Seek justice. Relieve the oppressed. Judge the fatherless. Plead for the widow."
