Chethib אנוּעך is a copyist's error. The thought requires the Hiphil אניעך (Keri), as נוּע in theKal has the intransitive meaning, to totter, sway about, or move hither and thither. “Return and take thy brethren back; grace and truth be with thee.” It is evidently more in accordance with the train of thought to separate עמּך from the previous clause and connect it with ואמת חסד, though this is opposed to the accents, than to adopt the adverbial interpretation, “take back thy brethren with thee in grace and truth,” as Maurer proposes. (For the thought itself, see Pro 3:3). The reference is to the grace and truth (faithfulness) of God, which David desired that Ittai should receive upon his way. In the Septuagint and Vulgate the passage is paraphrased thus: “Jehovah show thee grace and truth,” after 2Sa 2:6; but it by no means follows from this that עמּך ועשׂה והוה has fallen out of the Hebrew text.
Verse 21
But Ittai replied with a solemn oath, “Assuredly at the place where my lord the king shall be (stay),whether for death or life, there will thy servant be.” אם כּי means “only,” as in Gen 40:14, Job 42:8; here, in a declaration on oath, it is equivalent to assuredly (vid., Ewald, §356, b.). The Chethib is therefore correct, and the erasure of אם in the Keri is a bad emendation. The כּי in the apodosis is either an emphatic declaration, yea, or like ὅτι merely introduces a distinct assertion.
After this assurance of his devotedness, David let Ittai do as he pleased. ועבר לך, “go and pass on.” עבר does not mean to pass by, but to go forward. Thus Ittai and his men and all his family that was with him went forward with the king. By “the little ones” (taph) we are to understand a man's whole family, as in many other instances (see at Exo 12:37).
Verses 22-23
2Sa 15:22-23The king crosses the Kidron, and sends the priests back with the ark to Jerusalem. - 2Sa 15:23. All the land (as in 1Sa 14:25) wept aloud when all the people went forward; and the king went over the brook Kidron, and all the people went over in the direction of (lit. in the face of) the way to the desert. The brook Kidron is a winter torrent, i.e., a mountain torrent which only flows during the heavy rains of winter (χείμαῤῥος τοῦ Κεδρών, Joh 18:1). It is on the eastern side of Jerusalem, between the city and the Mount of Olives, and derives its name from the appearance of the water
