Who also were considered giants, as the Anakim; but the Moabites call them Emim.

Giants. Hebrew Raphaim, which Grotius thinks is a word retained from the primitive language. It sometimes denotes giants, and those who groan in hell, on account of the great iniquity of the Raphaim, Job. xxvi. 5. Og was one of their descendants, and inhabited the same country, which they had occupied in the days of Abraham, chap. iii. 2. (Calmet)
They lost much of their power in the war of Sodom. Some of them fled into the land of the Philistines, and established themselves there, 1 Kings xxi. 16. As these gigantic nations had been overthrown, as well as the Horrhites, when God formerly gave their territories to Moad and to Esau, (Haydock) so the Hebrews may be assured, that nothing will be able to resist their power, while He is with them. (Menochius)
