Why did he send only army officers?
Malbim (Divrei ha'Yamim II, 16:4): He did not need to send soldiers, for Aram's army was already there to help Basha. He sent only officers to command the soldiers to strike Basha.
Here it says "Avel Beis Ma'achah." In Divrei ha'Yamim II, 16:4 it says "Avel Mayim"!
Radak: These are the same.
What are "Kol Kinros"?
Radak: They are gatherings of Kineres.
Targum Yonasan: It is Ginosar. Radak - Chazal greatly praised the quality of its Peros (Megilah 6a). There were many such places, and all were fertile.
Why does it say "Al Kol Eretz Naftoli"?
Radak: This is like Im. Also "va'Yavo'u ha'Anashim Al ha'Nashim"(Shemos 35:22) means with the women. In Divrei ha'Yamim II, 16:4 it says "v'Es Kol Miskenos Arei Naftoli."
