“Rapha.” Rapha was one of the Nephilim, the “Fallen Ones.” Rapha is mentioned four times in this chapter: 2 Sam. 21:16, 18, 20, and 21:22 and in other places in the Old Testament as well. [For more on the Nephilim and the connection between them and Rapha, see commentary on Gen. 6:4].

“spear.” The Hebrew word for “spear” is uncertain, but “spear” is a likely candidate for the word.

“being armed with a new sword,” The Hebrew does not have an object, and the scholars are divided. Some say “sword,” others “armor,” and others mention other possibilities.
