'Supported' in the Bible

Moreover, He said to me, “Son of man, behold (listen carefully), I am going to break the staff of bread [that supports life] in Jerusalem; and they shall eat bread [rationed] by weight and [eat it] with anxiety and fear, and drink water by measure and [drink it] in horror [of the impending starvation],

‘Thus says the Lord,“Those who uphold and support Egypt will fallAnd the pride of her power will come down;From Migdol [in the north] to Syene [in the south]They will fall within her by the sword,”Says the Lord God.
