'Breasts' in the Bible

Whom will he teach knowledge? To whom will he explain the message? Those who are weaned from the milk, and drawn from the breasts?

Beat your breasts for the pleasant fields, for the fruitful vine.

You shall also drink the milk of the nations, and shall nurse from royal breasts; and you shall know that I, Yahweh, am your Savior, and your Redeemer, the Mighty One of Jacob.

that you may nurse and be satisfied at the comforting breasts; that you may drink deeply, and be delighted with the abundance of her glory."
