Yahweh is stating that Israel, spoken of here as a woman, is no longer acting like a wife to Yahweh. Instead Israel has turned away from following and worshiping him. (See: [[rc://en/ta/man/translate/figs-metaphor]])
A wife who is adulterous leaves her husband to sleep with another man. This is how Israel was acting toward Yahweh. (See: [[rc://en/ta/man/translate/figs-metaphor]])
Yahweh will no longer protect and provide for Israel because the nation has turned away from him. In Israel, husbands were obliged by law to provide clothes for their wives. Not to do so was a sign that a man was rejecting his wife. The full meaning of this may be made clear. (See: [[rc://en/ta/man/translate/figs-metaphor]] and [[rc://en/ta/man/translate/figs-explicit]])
Here "thirst" refers to the need to worship and rely on Yahweh, not idols, or Israel will not be able to survive as a nation. (See: [[rc://en/ta/man/translate/figs-metaphor]])
