'Labor' in the Bible

Then they journeyed from Bethel; and when there was still some distance to go to Ephrath, Rachel began to give birth and she suffered severe labor.

When she was in severe labor the midwife said to her, “Do not fear, for now you have another son.”

“When he saw that a resting place was goodAnd that the land was pleasant,He bowed his shoulder to bear burdens,And became a slave at forced labor.
