Matthew Henry Presbyterian @wholebiblehenry

Samuel, as a prophet, is here set over kings, Jer 1:10. I. He destroys king Agag, doubtless by such special direction from heaven as none now can pretend to. He hewed Agag in pieces. Some think he only ordered it to be done; or perhaps he did it with his own hands, as a sacrifice to God's injured justice (Sa1 15:33), and sacrifices used to be cut in pieces.

John Gill Reformed Baptist @doctorgill

And Samuel came no more to see Saul until the day of his death,.... Or "added not to see him" (x); not that he saw him no more, he saw him afterwards, Sa1 19:24, but it was accidentally, he did not go to see him, but Saul came to him; and Abarbinel supposes he might not see him then, but hid his face from him...
