James 2:8-10

Mace(i) 8 If, agreeably to the scriptures, you observe that royal law, "thou shalt love thy neighbour as thy self," you do well. 9 but partiality is iniquity; and the law will convict the offender of transgression. 10 for he that violates but one precept of the whole law, is as obnoxious to punishment, as if he had broke thro' all the rest.
