Commentary on Numbers 9:16

• Matthew Henry (Presbyterian), Matthew Henry's Complete Commentary on Numbers 9:15-23: We have here the history of the cloud; not a natural history: who knows the balancings of the clouds? but a divine history of a cloud that was appointed to be the visible sign and symbol of God's presence with Israel.
