שמואל ב טו:יט פירוש: רש״י

With the king. With Avsholom.

Because you are a foreigner. We are fleeing without provisions and food, and because you are a foreigner you will not find people that will have pity on you.

And even if you are estranged [from Avsholom]. And even if you are exiled from the king [Avsholom] because you do not want to be with him, then return to your home because it is not good to go with me because you [just] came yesterday.⁷This verse blends into verse 20 where Dovid explains more about why it is disadvantageous for Itai to stay with him.
