Charles Spurgeon Commentary Genesis 7:14

"they, and every beast after its kind, and all the cattle after their kind, and every creeping thing that creepeth upon the earth after its kind, and every bird after its kind, every bird of every sort." — Genesis 7:14 (ASV)

"Every bird of every sort," that is, every kind of bird; they are all mentioned again. God makes much of salvation. Oh, that we also did!

We may recount and rehearse the story of our rescue from universal destruction, and we need not be afraid or ashamed of repeating it. As the Holy Spirit repeats the words we have here, you and I may often recount the story of our salvation and dwell upon its minute particulars, for every item of it is full of instruction.
