But since a commandment is given respecting the continual observation (142) of the Sabbath, I postpone its explanation to a more appropriate place; except I would cursorily remark, that the proclamation of the blessing is annexed to the sign; because otherwise it would be an empty and unmeaning proceeding.

This indeed they had already done from the beginning, but with little constancy, because they had been so harassed by their afflictions as to neglect their duty; but now they correct the fault of ingratitude. Therefore, they not only declare their feelings of seriousness by bowing the head, but give actual proof of them; for it is expressly said, that they diligently performed whatever was commanded.
