Matthew Poole and continuators on Deuteronomy 22:8

8 When thou buildest a new house, then thou shalt make a battlement for thy roof, that thou bring not blood upon thine house, if any man fall from thence.

(i. e.) A fence or breastwork, because the roofs of their houses were made flat or plain, that men might walk on them See Iudg. 16. 27. 1 Sam. 9. 25. 2 Sam. 11. 2. Neh. 8. 16. Mat. 10. 27.

(i. e.) The guilt of blood, by a mans fall from the top of thy house, through thy neglect of this necessary provision.
