Isaiah 3:1
1For, behold, the Lord, GOD of Armies, takes away from Jerusalem and from Judah supply and support, the whole supply of bread, and the whole supply of water;
Behold, the Lord, GOD of Armies, takes away from Jerusalem and Judah supply and support, the whole supply of bread, and water.
The Lord actually removes what Judah leaned on. Bread and water were stays. Agency remains in the speech and deeds of v. 8 that drew this taking.
Calvin: behold presses the nearness of the hand. Wealth will not prevent wrath. Stay and staff: every kind of support, then bread and water first. God takes the strength of bread either by removing food or by withdrawing the hidden power that nourishes; without His blessing the full belly still hungers.
The secret blessing is His to give or withhold.
