Acts 9:5

The Lord; the Lord Jesus Christ. Ver Acts 9:17; Acts 9:27; 1Co 9:1; 1 Corinthians 15:8.

Hard; painful and useless.

Pricks; sharp irons or points at the end of a staff or goad with which they drove cattle. It was a proverbial expression, to denote that a person's efforts against others would only injure himself. In persecuting Christians, men injure not only others, but also themselves; and the further they proceed, the more they find that the way of transgressors is hard.
