and service of God, causing it to "pass", as the word (d) here used signifies, from a man's own power and use, to be the Lord's only: and every firstling that cometh from a beast which thou hast; or "even every firstling" (e), explaining what is meant by what opens the matrix or womb, even every firstborn of a beast; though Jarchi interprets it of an abortion, what comes before its time, that this also should be set apart to the Lord; this must be understood of the firstlings of clean creatures, fit for food and sacrifice, such as the firstlings of cows, sheep, and goats, Num 18:17 as distinguished from unclean ones in the following verse: the males shall be the Lord's; which explains what sort of firstborn of man and beast were to be set apart for his use, not females, though the first that opened the womb; but males. (d) "et transire facies", Pagninus, Montanus, Fagius, Vatablus, Drusius, Cartwright; so Ainsworth. (e) "etiam quicunque vel quicquid aperuerit", Junius & Tremellius, Piscator, Ainsworth.
