Look very carefully at the sentence structure. I know it might be difficult to miss, so I'll point it out.

(1 Samuel 20, NKJV)
41The youth hath gone, and David hath risen from Ezel, at the south, and falleth on his face to the earth, and boweth himself three times, and they kiss one another, and they weep one with another, till David exerted himself;
(1 Samuel 20, YLT)

(1 Samuel 20, NASB)
The word itself I've already posted in Strong's. The sentence works like this;
1Sa 20:41 [And] as soon as the lad was gone, David arose out of [a place] toward the south, and fell on his face to the ground, and bowed himself three time and they kissed one another, and wept one with another, until David exceeded.
