Yehoshua 10:18 Meaning and Commentary

Joshua 10:18

And Joshua said, roll great stones upon the mouth of the
cave
To keep the kings in, that they might not make their escape, until he had convenient time to have them brought before him, and be treated by him as they deserved; and no doubt there were plenty of stones about the hill or mountain, in which this cave was, fit for this purpose:

and set men by it for to keep them;
as a guard upon them, to prevent their escape.

Yehoshua 10:18 In-Context

16 But these five melachim fled, and hid themselves in a me’arah (cave) at Makkedah.

17 And it was told Yehoshua, saying, The five melachim are found hiding in a me’arah at Makkedah.

18 And Yehoshua said, Roll avanim gedolot upon the mouth of the me’arah, and post anashim by it to be shomer over them;

19 And stop ye not, but pursue after your enemies, and attack them; allow them not to enter into their towns; for Hashem Eloheichem hath delivered them into your yad.

20 And it came to pass, when Yehoshua and the Bnei Yisroel had made an end of striking them with a makkah gedolah me’od, until they were consumed, that the rest which remained of them entered into fortified cities.
