Now therefore make a new cart, and take two milch kine, on which there hath come no yoke, and tie the kine to the cart, and bring their calves home from them:

Wesley's Notes

6:7 Milch kine, and c. - In respect to the ark; and for the better discovery, because such untamed heifers are apt to wander, and keep no certain and constant paths, as oxen accustomed to the yoke do, and therefore were most unlikely to keep the direct road to Israel's land. From them - Which would stir up natural affection in their dams, and cause them rather to return home, than to go to a strange country.

Jamieson-Fausset-Brown Bible Commentary

7. make a new cart-Their object in making a new one for the purpose seems to have been not only for cleanliness and neatness, but from an impression that there would have been an impropriety in using one that had been applied to meaner or more common services. It appears to have been a covered wagon (see on [237]2Sa 6:3).

two milch kine-Such untrained heifers, wanton and vagrant, would pursue no certain and regular path, like those accustomed to the yoke, and therefore were most unlikely of their own spontaneous motion to prosecute the direct road to the land of Israel.

bring their calves home from them-The strong natural affection of the dams might be supposed to stimulate their return homewards, rather than direct their steps in a foreign country.

Matthew Henry's Concise Commentary

6:1-9 Seven months the Philistines were punished with the presence of the ark; so long it was a plague to them, because they would not send it home sooner. Sinners lengthen out their own miseries by refusing to part with their sins. The Israelites made no effort to recover the ark. Alas! where shall we find concern for religion prevail above all other matters? In times of public calamity we fear for ourselves, for our families, and for our country; but who cares for the ark of God? We are favoured with the gospel, but it is treated with neglect or contempt. We need not wonder if it should be taken from us; to many persons this, though the heavies of calamities, would occasion no grief. There are multitudes whom any profession would please as well as that of Christianity. But there are those who value the house, the word, and the ministry of God above their richest possessions, who dread the loss of these blessings more than death. How willing bad men are to shift off their convictions, and when they are in trouble, to believe it is a chance that happens; and that the rod has no voice which they should hear or heed!
