1 Kings 2:37

passest over the brook Kidron This brook, being between Jerusalem and the Mount of Olives, on that side of Jerusalem where Shimei would go if he wanted to return to Bahurim. Solomon takes the distance in this direction as a measure of bounds within which he must keep himself on every side. For in going afterwards to Gath he of course did not cross the brook Kidron.

thou shalt know The Hebrew often uses a future for an imperative. Here it is better to render - Know for certain" &c. It is so rendered in 1 Kings 2:42.
