'Strengthened' in the Bible

Look, you have instructed many; you have strengthened feeble hands.

Your words have supported those who stumbled, and you have strengthened the knees that gave way.

You have not strengthened the weak, healed the sick, bandaged the injured, brought back the strays, or sought the lost, but with force and harshness you have ruled over them.

Then the one who appeared to be a human being touched me again and strengthened me.

He said to me, "Don't be afraid, you who are valued. Peace be to you! Be strong! Be really strong!" When he spoke to me, I was strengthened. I said, "Sir, you may speak now, for you have given me strength."

Although I trained and strengthened them, they plot evil against me!
