“ That the tent here called the Tabernacle of the Congregation [5] is not the elaborate and costly structure specially built as the Lord directed, is evident from the fact that the greater and more enduring Tabernacle had not been constructed at the time referred to in the scripture last cited. Unlike the later Tabernacle, which was set up in the center of the camp with the tribes massed about it in specified order, this Provisional Tabernacle was pitched outside the camp—afar off—perhaps as an indication of the Lord's withdrawal following Israel's idolatrous turning away from Him. ”
