'Sustaining' in the Bible

“Because these people (Judah) have refused the gently flowing waters of ShiloahAnd rejoice in Rezin [the king of Aram] and Remaliah’s son [Pekah the king of Israel],

But whoever has the world’s goods (adequate resources), and sees his brother in need, but has no compassion for him, how does the love of God live in him?
