Exodus 31:12-17

Some have thought, that the repeating the commandment respecting the sabbath in this place, was with this intention; lest the children of Israel should suppose, that while building the tabernacle, which was now to be set about, they might, as it was God's work, go on with the continuance of the work on God's day. Hence they were taught, that even the works for God must not break in upon the holy day of God. Oh! how much to be wished is it, that Christians would remember this!
