Adonijah’s feast was probably of a sacrificial character, and intended to inaugurate him as king. Compare the “sacrifices” of Absalom 2 Samuel 15:12.
Zoheleth - No satisfactory explanation has been given of this name. Large blocks of stone always attract attention in the East, and receive names which are often drawn from some trivial circumstance. Sinai and Palestine are full of such “Hajars,” which correspond to the “Ebens” or “stones” of Holy Scripture. (Compare Genesis 28:22; Jos 4:9; 1 Samuel 6:14.) For En-Rogel, see the margin reference.
