Moses, Aaron, and Hur went up. — Moses, we know, was eighty years of age (Exodus 7:7); Aaron was eighty-three; Hur, the grandfather of Bezaleel (Exodus 31:2), the architect of the Tabernacle, can scarcely have been less. Unfit for battle themselves, they felt it was by prayer and intercession that they could best help forward a good result, and so withdrew themselves from the actual conflict to a place where they could command it.
Hur. — According to Jewish tradition (Joseph., Ant. Jud., iii. 2, § 4) Hur was the husband of Miriam, and so the brother-in-law of Moses and Aaron. He was a descendant of Judah through Pharez and Hezron. (1 Chronicles 2:3-20.) Moses left him joint regent with Aaron When he ascended up into Sinai (Exodus 24:14).
