וְיוֹאָ֥ב בֶּן־צְרוּיָ֖ה עַל־הַצָּבָ֑א וִיהוֹשָׁפָ֥ט בֶּן־אֲחִיל֖וּד מַזְכִּֽיר׃
Si Joab na anak ni Zeruia ang namumuno sa hukbo, at si Josafat na anak ni Ahilud ang tagapagtala.
Rashi
Now Joab, etc. was over the host Since he retired from going with the army, he placed Joab over the host to wage all his battles. All this refers back to “... and he administered justice and charity.” The interruption with “Now Joab, etc. was over the host,” was necessary for the following reason, lest you say that since “... and David was administering justice,” [the result was that] the Israelites were no longer waging war, therefore, it says “Now Joab was over the host.”
Rashi
recorder - Heb. הַמַּזְכִּיר, lit., the reminder. This refers back to the beginning (verse 14), that he would remind [him of] which case came before the king first, and a similar instance is (Esther 6:1): “... to bring... the records (הַזִּכְרוֹנוֹת), the chronicles.”
