There; not in the most holy place, wherein only the priests might eat, Numbers 18:10, but more generally in places allowed to the people for this end in the holy city. Ye shall eat, to wit, your part of the things mentioned Deuteronomy 12:6. Before the Lord, i.e. in the place of God's presence, where God's sanctuary shall be. All that ye put your hand unto; either to bestow your pains and labour upon it; or, to take and use or enjoy it. The sense is, You thus doing shall be blessed and enabled to rejoice, or to take comfort in all your labours and enjoyments, which otherwise would be accursed to you. We have the same phrase below, Deuteronomy 12:18, Deuteronomy 15:10.
