'Relieve' in the Bible

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."

If any man or woman who believes has widows, let them relieve them, and don't let the assembly be burdened; that it might relieve those who are widows indeed.
