Genesis 1:3 is the third verse of the first chapter in the Book of Genesis. In it God made light by declaration: God said, ‘Let there be light,’ and there was light. It is a part of the Torah portion known as Bereshit (Genesis 1:1-6:8).
And he that is to be cleansed shall wash his clothes, and shave off all his hair, and wash himself in water, that he may be clean: and after that he shall come into the camp, and shall tarry abroad out of his tent seven days.Leviticus 14:8 KJV
