Shmuel Alef 4:6

6 And when the Pelishtim (Philistines) heard the kol hateruah, they said, What meaneth kol hateruah hagedolah hazot in the machaneh HaIvrit? And they understood that the Aron Hashem was come into the machaneh.

Shmuel Alef 4:6 Meaning and Commentary

1 Samuel 4:6

And when the Philistines heard the noise of the shout
For it being so loud as to make the earth ring, it was heard in the camp of the Philistines, which might not be at any great distance from the camp of Israel; how far from each other were Aphek and Ebenezer is not certain;

they said, what meaneth the noise of this great shout in the camp of
the Hebrews?
they could not conceive what should be the reason of it, seeing they had no occasion to shout for joy, having been lately defeated; and a shout is made generally just before a battle is begun, and the onset made, or when victory is obtained; neither of which was the case now:

and they understood that the ark of the Lord was come into the camp:
this they understood by spies, which they sent to find out the meaning of the shout; which is more probable than that they came to the knowledge of it by deserters; seeing it is not very likely that any Israelites would desert to the Philistines.

Shmuel Alef 4:6 In-Context

4 So HaAm sent to Shiloh, that they might bring from there the Aron Brit Hashem Tzva’os, Who dwelleth between the keruvim; and the two Bnei Eli, Chophni and Pinchas, were there with the Aron Brit HaElohim.

5 And when the Aron Brit Hashem came into the machaneh, kol Yisroel shouted with a teru’ah gedolah, so that ha’aretz shook.

6 And when the Pelishtim (Philistines) heard the kol hateruah, they said, What meaneth kol hateruah hagedolah hazot in the machaneh HaIvrit? And they understood that the Aron Hashem was come into the machaneh.

7 And the Pelishtim (Philistines) were afraid, for they said, elohim is come into the machaneh. And they said, Oy lanu! For there hath not been such a thing as this heretofore.

8 Oy lanu! Who shall save us out of the yad of these elohim ha’adirim (mighty g-ds)? These are the g-ds that struck the Mitzrayim with kol makkah (all the plagues) in the midbar.
