2 Samuel 17:16

Now therefore send quickly and tell David
What has been advised to on both sides:

saying, lodge not this night in the plains of the wilderness;
which reached to Jericho; this advice he gave, because he knew not whether his counsel would be abode by, though preferred; Absalom and the elders of Israel might change their minds, and Ahithophel might, by the strength of his oratory, prevail upon them after all to follow his advice; and therefore, to guard against the worst, he judged it most prudential in David to make all the haste he could from that place where he was, and not continue a night longer in it; for, if Ahithophel's counsel should take place, he would be in pursuit of him that very night:

but speedily pass over;
the river Jordan:

lest the king be swallowed up, and all the people that [are] with him:
be destroyed by the forces Ahithophel should bring with him, which he would not be able to withstand.
