Matthew Poole and continuators on Exodus 21:14

14 But if a man come presumptuously upon his neighbour to slay him with guile, thou shalt take him from mine Altar , that he may die.

(i. e.) Do this proudly, boldly, purposely and malitiously; for so the word signifies.

Which not onely in the wilderness, but afterward, seems to have been esteemed a place of refuge, 1 King. 1. 50. as it also was among the Heathens: But God so far abhors murder, that he will rather venture the pollution of his own Altar than the escape of the murderer. See 2 King. 11. 15.
