John Gill's Exposition of the Whole Bible
2 Samuel 10:5
When they told [it] unto David,.... Not the ambassadors, for they were not yet arrived, but some of their servants, perhaps, they sent before them to acquaint David of the usage they had met with:
he sent to meet them: he sent men to meet them with proper garments to put on, and to assure them how much he resented the indignity done to them and him, and would avenge it in due and proper time, and to direct them where to go for the present, as follows:
because the men were greatly ashamed: to proceed on their journey, and come to court in the condition they were:
and the king said; gave orders by the messengers he sent to them:
tarry at Jericho until your beards be grown, or "bud" t,
and [then] return; that is, to Jerusalem; Jericho, though not yet built, might have some cottages at or near the spot on which it had stood, for the convenience of shepherds, and gatherers of fruit, in the plains of it; here the ambassadors were directed to go, it being the first place they came to when they had passed over Jordan, from the country of Ammon; and being a place where there were scarcely any inhabitants, or very few, was very proper for them in their present circumstances; and this confirms what is before observed, that it was now the custom of the Israelites not to shave their whole beards; or otherwise it was but shaving off the other half, and being now provided with other clothes, they would have had no need to have stayed at Jericho, but might have proceeded on in their journey.
