¹ tn The Piel participle מְקַנֵּא (m^eqanneʾ) serves as a verb here in this interrogative sentence. The word means “to be jealous; to be envious.” That can be in a good sense, such as with the translation “zeal,” or it can be in a negative sense as here. Joshua’s apparent “zeal” is questioned by Moses—was he zealous/envious for Moses sake, or for some other reason?

¹ tn Grk “in the gall of bitterness,” an idiom meaning to be particularly envious or resentful of someone. In this case Simon was jealous of the apostles’ power to bestow the Holy Spirit by the laying on of hands, and wanted that power for himself. The literal phrase does not convey this to the modern reader, and in fact some modern translations have simply rendered the phrase as involving bitterness, which misses the point of the envy on Simon’s part. See L&N 88.166. The OT images come from Deut 29:17-18 and Isa 58:6.

² sn It may be that Miriam was envious of the Cushite woman Moses married. And, in view of the previous chapter’s content about others being given a portion of the Spirit to share in the leadership role, she may have seen this as her chance finally to become just as important in the nation as her younger brother. After all, she safeguarded his birth and early years (Exod 2). But there are two issues here—the reason she gives (“does the Lord only speak through Moses?”), and the reason the text gives (the Cushite woman).

⁴ tn Interpreters debate the referent of the word “spirit” in this verse: (1) The translation takes “spirit” to be the lustful capacity within people that produces a divided mind (1:8, 14) and inward conflicts regarding God (4:1-4). God has allowed it to be in man since the fall, and he provides his grace (v. 6) and the new birth through the gospel message (1:18-25) to counteract its evil effects. (2) On the other hand the word “spirit” may be taken positively as the Holy Spirit and the sense would be, “God yearns jealously for the Spirit he caused to live within us.” But the word for “envious” or “jealous” is generally negative in biblical usage and the context before and after seems to favor the negative interpretation.

¹ sn In this short chapter we find a prime example of jealousy among leaders and how God dealt with it. Miriam and Aaron are envious of Moses’ leadership, but they use an occasion—his marriage—to criticize him. Often the immediate criticism is simply a surface issue for a deeper matter. God indicates very clearly he will speak through many people, including them, but Moses is different. Moses is the mediator of the covenant. The chapter is a lesson of what not to do. They should have fulfilled their duties before God and not tried to compete or challenge the leader in this way. There is a touch of divine irony here, for Miriam is turned white with leprosy. The chapter falls easily into the sections of the story: the accusation (vv. 1-3), the Lord’s response (vv. 4-10), the intercession of Moses (vv. 11-16). For further information, see J. S. Kselman, “A Note on Numbers 12:6-8, ” VT 26 (1976): 500-504.
