'Pangs' in the Bible

when they crouch down to give birth to their offspring, and let go of their birth pangs?

Therefore my body is racked with pain; pangs have seized me, like the pangs of a woman in labor; I am so upset that I cannot hear; I am so frightened that I cannot see while I'm reeling around.

For fools utter contempt, and their minds plot wrong things: practicing ungodliness, spreading lies about the LORD, leaving the pangs of hungry people unsatisfied, and depriving thirsty people of drink.
