John Gill Commentary 2 Kings 7:4

"If we say, We will enter into the city, then the famine is in the city, and we shall die there; and if we sit still here, we die also. Now therefore come, and let us fall unto the host of the Syrians: if they save us alive, we shall live; and if they kill us, we shall but die." — 2 Kings 7:4 (ASV)

If we say we will enter into the city
Contrary to the law which forbid them:

then the famine is in the city, and we shall die there ;
not being able to obtain food to preserve life:

and if we sit here, we die also ;
having nothing to eat to support nature:

now therefore let us come, and fall unto the host of the Syrians ;
put ourselves into their hands, and lie at their mercy:

if they save us alive, we shall live ;
if they do not put us to death, but give us bread to eat, our lives will be preserved:

and if they kill us, we shall but die ;
which we must inevitably do, whether we stay here, or go into the city.
