Melachim Bais 13:7

7 For he [Melech Aram] did leave of the army to Yehoachaz but 50 parashim, and 10 merkavot, and 10,000 foot soldiers; for Melech Aram had destroyed them, and had made them like the aphar for trampling.

Melachim Bais 13:7 Meaning and Commentary

2 Kings 13:7

Neither did he leave of the people to Jehoahaz but fifty
horsemen
This is to be connected with ( 2 Kings 13:4 ) , the verses ( 2 Kings 12:5 2 Kings 12:6 ) , being to be read in a parenthesis, as in our version, and to be understood of the king of Syria, who left no more to the king of Israel, not of the people of the land, but of his army, than fifty horsemen, all the rest being either taken and carried captive by him, or slain:

and ten chariots;
military chariots, with the men they carried:

and ten thousand footmen;
foot soldiers; to so small a number was his army reduced through wars with the Syrians:

for the king of Syria had destroyed them, and had made them like the
dust by threshing:
as corn or chaff may be reduced to dust by too much threshing; or as mire and clay by treading on it.

Melachim Bais 13:7 In-Context

5 And Hashem gave Yisroel a moshia (savior), so that they went out from under the yad Aram; and the Bnei Yisroel dwelt in their ohalim, as formerly.

6 Nevertheless they departed not from the chattot of the Bais Yarov‘am, who made Yisroel sin, but walked therein; and also there remained standing the Asherah in Shomron—

7 For he [Melech Aram] did leave of the army to Yehoachaz but 50 parashim, and 10 merkavot, and 10,000 foot soldiers; for Melech Aram had destroyed them, and had made them like the aphar for trampling.

8 Now the rest of the acts of Yehoachaz, and all that he did, and his gevurah, are they not written in the Sefer Divrei HaYamim L’Malkhei Yisroel?

9 And Yehoachaz slept with his avot; and they buried him in Shomron; and Yoash bno reigned as Melech in his place.
