Matthew Poole and continuators on 2 Samuel 12:20

20 Then David arose from the earth, and washed, and anointed himself, and changed his apparel, and came into the house of the LORD , and worshipped: then he came to his own house, and when he required, they set bread before him, and he did eat.

i. e. To the Tabernacle, to confess his Sin before the Lord, and to own his Justice in this stroke, and the other threatnings, and to deprecate his great and just displeasure, and to acknowledge Gods rich mercy, in sparing his own Life; and to offer such Sacrifices as were proper and required in such cases. Nor did David transgress that Law, Numb. 19. 14. in going thither before the Seven Days were expired. For neither is there the same reason of a Tent, and of a dwelling House, where the several Rooms of the House are as distinct as several Tents; nor is it here said, that David was in the same Room, or in the same House where the Child died.
