Furthermore, the first-born of both man and beast were to be the Lord’s, to be bought back only by a ransom, in acknowledgment that when the first-born in Egypt perished, that of Israel, though graciously preserved, had been justly exposed to the same doom but for the atoning sacrifice. “All the first-born are Mine,” the Lord declared; “for on the day that I smote all the first-born in the land of Egypt, I hallowed unto Me all the first-born in Israel, both man and beast: Mine they shall be,” Numbers 3:13L. After the institution of the tabernacle service the Lord chose unto Himself the tribe of Levi for the work of the sanctuary, instead of the first-born of the people. “They are wholly given unto Me from among the children of Israel,” He said. “Instead of the first-born of all the children of Israel, have I taken them unto Me.” Numbers 8:16L. All the people were, however, still required, in acknowledgment of God’s mercy, to pay a redemption price for the first-born son. Numbers 18:15, 16L.
