'Support' in the Bible

Strengthen the feeble hands, and support the stumbling knees.

"Here is my servant, whom I support, my chosen one, in whom I delight. I've placed my Spirit upon him; and he'll deliver his justice throughout the world.

I looked, but there was no helper, I was appalled that there was no one to give support; so my own arm brought me victory, and as for my wrath, it supported me.
