All measure - All measures used either in sacred or civil things, the publick standards whereof were kept in the temple; and therefore the care of keeping them inviolable and producing them upon occasion, musts needs belong to the priests, and under them to the Levites, who were to examine other measures and all things by them, as occasion required; that so the priests might be at leisure for their higher and greater employments.
Verse 30. Morning and even - The two solemn times of offering sacrifices: which work was attended with publick prayer and thanksgiving.
Verse 32. Charge - What the priests should commit to their charge, or command them to do.
