'Strengthen' in the Bible

For the seller to the sold thing turneth not, And yet among the living is their life, For the vision is unto all its multitude, It doth not turn back, And none by his iniquity doth strengthen his life.

The arm of Pharaoh, king of Egypt, I have broken, And lo, it hath not been bound up to give healing, To put a bandage to bind it, To strengthen it -- to lay hold on the sword.

The lost I seek, and the driven away bring back, And the broken I bind up, and the sick I strengthen, And the fat and the strong I destroy, I feed it with judgment.
