Matthew Poole and continuators on Jeremiah 14:8

8 O the hope of Israel , the Saviour thereof in time of trouble , why shouldst thou be as a stranger in the land, and as a wayfaring man, that turneth aside to tarry for a night ?

That is the object of Israels hope, he in whom alone thy people Israel have been wont to hope, or he in whom alone Israel hath just reason to hope.

Thou who hast formerly been their Saviour in the times of their trouble, or who alone canst save them in such times of trouble, as thou hast now brought them into, see Psal. 9.9. & 46.1.

Why shouldst thou be as one that regardest thy ancient people no more then a Stranger, or a Traveller, who taketh no farther care for the place, or the house where he lodgeth, then for the short time that he is to stay or abide in it.
