It is truly interesting to see the zeal of the faithful. How jealous for the honour of GOD was Moses? In regarding the LORD'S glory, he passeth by all lesser considerations. Angels burn with an holy flame in this particular. We have a striking instance of one of the heavenly host manifesting his warmth of zeal for the glory of GOD, in the instance of the death of Herod. Acts 12:23. And if the Reader would behold the account of one infinitely greater than the angels, he may read how the prophet described him under this feature, as clad with zeal as a cloke; and how the evangelist interpreted this when he appeared in substance of our flesh. See Isaiah 59:17; Psalms 69:9; John 2:15-17.
Numbers 31:13-18
13 And Moses, and Eleazar the priest, and all the princes of the congregation, went forth to meet them without the camp.
14 And Moses was wroth with the officers of the host, with the captains over thousands, and captains over hundreds, which came from the battle.a
15 And Moses said unto them, Have ye saved all the women alive?
16 Behold, these caused the children of Israel, through the counsel of Balaam, to commit trespass against the LORD in the matter of Peor, and there was a plague among the congregation of the LORD.
17 Now therefore kill every male among the little ones, and kill every woman that hath known man by lying with him.b
18 But all the women children, that have not known a man by lying with him, keep alive for yourselves.
