Verse 18 And I will establish My covenant with you; and you shall enter into the ark, you, and your sons, and your wife, and your sons' wives with you. 'Establishing a covenant' means that he would be
regenerated. 'He was to enter into the ark, he and his sons, [and his wife,] and his sons' wives' means that he would be saved, sons' being truths and 'wives' goods.
