And Samuel said, “As your sword has made women childless, so shall your mother be childless among women.” And Samuel hacked Agag to pieces before the Lord in Gilgal. (ESV)
Samuel declared:
As your sword has made women childless, so your mother will be childless among women.
Then he hacked Agag to pieces before the Lord at Gilgal. (HCSB)
However, Samuel said: “Just as your sword has bereaved women of children, so your mother will be most bereaved among women.” With that Samuel hacked Aʹgag to pieces before Jehovah at Gilʹgal. (NWT 2013)
Robert Alter translates part of 1 Samuel 15:33 this way: "And Samuel cut him apart before the LORD at Gilgal." He then offers these remarks:
Samuel cut him apart before the LORD. "There is a long-standing consensus that the unique verb used here means something to this effect. The ghastly idea seems to be a kind of ritual butchering."
See The David Story, page 93.
A. Graeme Auld gives these comments (I and II Samuel: A Commentary, Page 175):
"33a. How precisely Samuel dispatches Agag is unclear: this is the unique instance of šsp (mt) in hb. The traditional 'dismember' presupposes a link with the later biblical šṣp. The gt’s choice of esphaxen may have been influenced by two sibilants followed by p in the unfamiliar Hebrew."
On page 180, Auld writes: "The slaying of Agag has features of both execution and sacrifice. Samuel’s judgment that the punishment will fit the crime suggests criminal process. and yet what happens is not simply 'at Gilgal' but 'before Yahweh' or 'in Yahweh’s presence' (in this respect, his death anticipates the death of seven of Saul's family in 2 Sam 21:9). There are regular elements of due order, or ritual, in judicial executions; but given the opaqueness of the unique verb šsp, it is unwise to say more."
From David Tsumura's 1 Samuel Commentary:
And Samuel hewed Agag to pieces: McCarter thinks that the LXX translation and the fact that it was done “before the Lord” suggest “sacrificial butchering.” He suggests that “cutting” in covenant ceremonies symbolized the punishment of covenant breakers, and therefore the Amalekites at the time of Moses had broken a covenant with Israel.⁹⁷ However, as Hertzberg holds, Samuel's action rather “takes the event from the sphere of sacrifice into that of the ban”; see the punishment of Achan in Joshua 7. Instead of Saul, Samuel completed the performance of the “ban” on the Amalekites, devoting Agag their king to the Lord.
