'Instead' in the Bible

Adam knew his wife again. She gave birth to a son, and named him Seth, "for God has appointed me another child instead of Abel, for Cain killed him."

Abraham lifted up his eyes, and looked, and saw that behind him was a ram caught in the thicket by his horns. Abraham went and took the ram, and offered him up for a burnt offering instead of his son.

Now therefore, please let your servant stay instead of the boy, a bondservant to my lord; and let the boy go up with his brothers.
