Fall unto — i.e., desert, go over to.
If they save us alive. — And give us food, for pity’s sake.
We shall but die. — As we shall if we stop here, or if we go into the city. (The “but” is not in the Hebrew.)

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.
