Verse 33. "As thy sword hath made women childless" - It appears that Agag had forfeited his life by his own personal transgressions, and that his death now was the retribution of his cruelties.
"And Samuel hewed Agag in pieces" - 1. What Samuel did here he did in his magisterial capacity; and, 2. It is not likely he did it by his own sword, but by that of an executioner. What kings, magistrates, and generals do, in an official way, by their subjects, servants, or soldiers, they are said to do themselves; qui facit per alterum, facit per se.
Verse 35. "And Samuel came no more to see Saul" - But we read, 1 Sam. xix. 22-24, that Saul went to see Samuel at Naioth, but this does not affect what is said here. From this time Samuel had no connection with Saul; he never more acknowledged him as king; he mourned and prayed for him, and continued to perform his prophetic functions at Ramah, and at Naioth, superintending the school of the prophets in that place.
