Exodus 26:15 - Clarke's commentary and critical notes on the Bible

And thou shalt make boards for the tabernacle of shittim wood standing up. Thou shalt make boards - These formed what might be called the walls of the tabernacle, and were made of shittim wood, the acacia Nilotica, which Dr. Shaw says grows here in abundance. To have worked the acacia into these boards or planks, the Israelites must have had sawyers, joiners, etc., among them; but how they got the tools is a question. But as the Israelites were the general workmen of Egypt, and were brought up to every kind of trade for the service of their oppressors, we may naturally suppose that every artificer brought off some of his tools with him. For though it is not at all likely that they had any armor or defensive weapons in their power, yet for the reason above assigned they must have had the implements which were requisite for their respective trades.
