'Release' in the Bible

so I will stretch out my hand and strike Egypt with all my wonders that I will do there. After that he will release you.

"If a man strikes the eye of his male or female servant and destroys it, he is to release him as a free man in exchange for his eye.

If he knocks out the tooth of his male or female servant, he is to release him as a free man in exchange for his tooth.
