The sons of Shelah the son of Judah were, Er the father of Lecah, and Laadah the father of Mareshah, and the families of the house of them that wrought fine linen, of the house of Ashbea,

Wesley's Notes

4:21 Shelah - Having treated of the posterity of Judah by Pharez, and by Zara, he now comes to his progeny by Shelah.

Jamieson-Fausset-Brown Bible Commentary

1Ch 4:21-23. Posterity of Shelah.

21. Laadah . the father . of the house of them that wrought fine linen-Here, again, is another incidental evidence that in very early times certain trades were followed by particular families among the Hebrews, apparently in hereditary succession. Their knowledge of the art of linen manufacture had been, most probably, acquired in Egypt, where the duty of bringing up families to the occupations of their forefathers was a compulsory obligation, whereas in Israel, as in many parts of Asia to this day, it was optional, though common.

Matthew Henry's Concise Commentary

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.
