What does 2 Samuel 20:4 mean?

John Gill's Exposition of the Bible
2 Samuel 20:4

Then said the king to Amasa
Whom he had promised to make general of his army, ( 2 Samuel 19:13 ) ; and by the following order declared him such:

assemble me the men of Judah within three days;
which was done by the sound of the trumpet, or by the proclamation of a herald; it seems that the men of Judah, who attended David to Jerusalem, were gone to their respective cities and places of abode, or there would have been no occasion for such a summons; though it is strange they should, when the men of Israel appeared so inclinable to a new rebellion:

and be thou here present;
to take the command of them.
