And it came to pass, as she came unto him, that she moved him to ask of her father a field: {f} and she lighted off her ass; and Caleb said unto her, What wouldest thou?

(f) Because her husband tarried too long.

Wesley's Notes

15:18 As she came - Or, as she went, namely, from her father's house to her husband's, as the manner was. She moved him - She persuaded her husband, either, That he would ask: or rather, That he would suffer her to ask, as she did. She lighted - That she might address herself to her father in an humble posture, and as a suppliant, which he understood by her gesture.

Jamieson-Fausset-Brown Bible Commentary

18, 19. as she came unto him-that is, when about to remove from her father's to her husband's house. She suddenly alighted from her travelling equipage-a mark of respect to her father, and a sign of making some request. She had urged Othniel to broach the matter, but he not wishing to do what appeared like evincing a grasping disposition, she resolved herself to speak out. Taking advantage of the parting scene when a parent's heart was likely to be tender, she begged (as her marriage portion consisted of a field which, having a southern exposure, was comparatively an arid and barren waste) he would add the adjoining one, which abounded in excellent springs. The request being reasonable, it was granted; and the story conveys this important lesson in religion, that if earthly parents are ready to bestow on their children that which is good, much more will our heavenly Father give every necessary blessing to them who ask Him.

Matthew Henry's Concise Commentary

15:13-19 Achsah obtained some land by Caleb's free grant. He gave her a south land. Land indeed, but a south land, dry and apt to be parched. She obtained more, on her request, and he gave the upper and the nether springs. Those who understand it but of one field, watered both with the rain of heaven, and the springs that issued out of the earth, countenance the allusion commonly made to this, when we pray for spiritual and heavenly blessings which relate to our souls, as blessings of the upper springs, and those which relate to the body and the life that now is, as blessings of the nether springs. All the blessings, both of the upper and the nether springs, belong to the children of God. As related to Christ, they have them freely given of the Father, for the lot of their inheritance.
