Numbers Chapter 12
After that (for what form will not rebellion assume?) Miriam and Aaron speak against Moses. It is the prophetess and the priest (one who has the word from God and access to God, the twofold character of the people of God), who rise up against him who is king in Jeshurun, with whom God speaks as unto His friend. In this Moses is in all respects a type of Christ, who stands personally outside the rights which grace has conferred upon the people. Faithful in all the house of God, he enjoys close intercourse with Him. Miriam and Aaron ought to have been afraid. The excuse of the two rebels was, that Moses had taken an Ethiopian woman-a blessed sign for us of the sovereignty of grace which has introduced into the blessing of Christ those who had no right or title to it. The people of God, whatever their privileges, ought to have recognised this sovereignty. Israel would not, and was smitten with leprosy. It is, however, in their character of witness or prophet that they suffer this chastening.
Aaron resumes his place of intercessor, and speaks humbly to Moses (a figure, I think, of the humiliation of Israel, grounded on the value of the intercession of Christ, identifying Himself with the position of the people). God's answer is, that Miriam should be humbled and chastened, shut out, for a time, from intercourse with Him, then restored to favour again. The people wait for her restoration. Let us remember that the Lord here recalls this fact, that the most glorious position for Moses was that when he was separated from the people-when he pitched his tent without the camp, and called it the tabernacle of the congregation or meeting. The people had but too much forgotten this. When the members of the church also, in the thought of making themselves spiritual, take advantage of their glory and position as prophets and priests (characters which do indeed belong to them), to disown the rights of Christ, as king in Jeshurun, having authority over the house of God, there is room for considering whether they are not guilty of the rebellion here spoken of. For my part, I believe they are.
