2 Kings 3:6

went out of Samaria the same time R.V. at that time. The time indicated is probably the occasion of the first refusal of the tribute to Jehoram. He might perhaps regard the former refusal, which no doubt had been given to Ahaziah, as prompted by the knowledge that the king of Israel was weak and unfit for war, and so there was a good opportunity to strive for freedom. Hence he would wait till the season came round, and prepare his campaign when he found that he was to be treated with the same measure as his brother.

and numbered R.V. mustered. The verb implies a good deal more than the mere numbering. It includes all the inspection necessary to find whether an army is ready for war. Hence the king gathered the troops outside Samaria. The word -muster" is the rendering of one form of this verb in A.V. (Isaiah 13:4) but in most other passages -number" is used for it. What Jehoram did was to gather together all the men of war from the ten tribes to a camp near Samaria and when all was arranged to start on his march.
