And some of them, even of the sons of Simeon, five hundred men went to Mount Seir,.... In the land of Edom:

having for their captains Pelatiah, and Neariah, and Rephaiah, and Uzziel, the sons of Ishi; these four captains are said, by the ancient Rabbins, to be of the tribe of Manasseh, as Kimchi observes; see 1 Chronicles 5:24 but as the five hundred they were at the head of were of the sons of Simeon, the captains, no doubt, were of the same race.

A part of the Simeonites undertook a second war of conquest against Mount Seir. Led by four chiefs of the sons of Shimei (cf. 1 Chronicles 4:27), 500 men marched thither, smote the remainder of the Amalekites who had escaped, and they dwell there to this day (as in 1 Chronicles 4:41). מהם is more accurately defined by שׁ מבּני, and is therefore to be referred to the Simeonites in general, and not to that part of them only mentioned in 1 Chronicles 4:33 (Berth.). From the circumstance that the leaders were sons of Shimei, we may conclude that the whole troop belonged to this family. The escaped of Amalek are those who had escaped destruction in the victories of Saul and David over this hereditary enemy of Israel (1 Samuel 14:48; 1 Samuel 15:7; 2 Samuel 8:12). A remnant of them had been driven into the mountain land of Idumea, where they were smitten, i.e., extirpated, by the Simeonites. It is not said at what time this was done, but it occurred most probably in the second half of Hezekiah's reign.

And some of them, even of the sons of Simeon, five hundred men, went to mount Seir, having for their captains Pelatiah, and Neariah, and Rephaiah, and Uzziel, the sons of Ishi.

4:1-43 Genealogies. - In this chapter we have a further account of Judah, the most numerous and most famous of all the tribes; also an account of Simeon. The most remarkable person in this chapter is Jabez. We are not told upon what account Jabez was more honourable than his brethren; but we find that he was a praying man. The way to be truly great, is to seek to do God's will, and to pray earnestly. Here is the prayer he made. Jabez prayed to the living and true God, who alone can hear and answer prayer; and, in prayer he regarded him as a God in covenant with his people. He does not express his promise, but leaves it to be understood; he was afraid to promise in his own strength, and resolved to devote himself entirely to God. Lord, if thou wilt bless me and keep me, do what thou wilt with me; I will be at thy command and disposal for ever. As the text reads it, this was the language of a most ardent and affectionate desire, Oh that thou wouldest bless me! Four things Jabez prayed for. 1. That God would bless him indeed. Spiritual blessings are the best blessings: God's blessings are real things, and produce real effects. 2. That He would enlarge his coast. That God would enlarge our hearts, and so enlarge our portion in himself, and in the heavenly Canaan, ought to be our desire and prayer. 3. That God's hand might be with him. God's hand with us, to lead us, protect us, strengthen us, and to work all our works in us and for us, is a hand all-sufficient for us. 4. That he would keep him from evil, the evil of sin, the evil of trouble, all the evil designs of his enemies, that they might not hurt, nor make him a Jabez indeed, a man of sorrow. God granted that which he requested. God is ever ready to hear prayer: his ear is not now heavy.
