Adam Clarke on Genesis 35:16

There was but a little way to come to Ephrath - The word כברת kibrath, translated here a little way, has greatly perplexed commentators. It occurs only here, in Gen 48:7, and 2Kgs 5:19; and it seems to have been some sort of measure applied to land, as we say a mile, an acre, a rood, a perch; but what the exact quantity of the kibrath was cannot be ascertained. Ephrath, called also Bethlehem, and Bethlehem Ephrata, was the birthplace of our blessed Redeemer. See its meaning Mat 2:6 (note).
