'Support' in the Bible

Son of man, when a land, sinning against me, does wrong, and my hand is stretched out against it, and the support of its bread is broken, and I make it short of food, cutting off man and beast from it:

And it will be clear to all the people of Egypt that I am the Lord, because you have been a false support to the children of Israel.

When they took a grip of you in their hands, you were crushed so that their arms were broken: and when they put their weight on you for support, you were broken and all their muscles gave way.
