The distinction between the ark and the people is not noticed for nothing. No doubt much is couched under it. And it may, perhaps, be intended to show, that as the ark rested in the water until all the people were secured from danger, so Jesus, whom the ark represented, will remain with the hindmost of his redeemed ones until every hoof is in safety. Precious Jesus! as thou art first, so last in everything which concerns redemption-work, that in all things thou mightest have the pre-eminence. Colossians 1:17-18.
