Charles Ellicott Commentary Genesis 2:18

"And Jehovah God said, It is not good that the man should be alone; I will make him a help meet for him." — Genesis 2:18 (ASV)

It is not good ... — In these words we have the Divine appointment of marriage, and also the declaration that the female is subsequent in order of production to the male, and formed from him. In Genesis 1:27; Genesis 5:2, the creation of male and female is represented as having been simultaneous. She is described as a help meet for him: in Hebrew, a help as his front, his reflected image, or, as the Syriac translates it, a helper similar to him. The happiness of marriage is based, not upon the woman being just the same thing as the man, but upon her being one in whom he sees his image and counterpart.
