Charles Ellicott Commentary 2 Chronicles 28:13

"and said unto them, Ye shall not bring in the captives hither: for ye purpose that which will bring upon us a trespass against Jehovah, to add unto our sins and to our trespass; for our trespass is great, and there is fierce wrath against Israel." — 2 Chronicles 28:13 (ASV)

You shall not bring in. —Into the city.

Whereas we ... already. —This is at least a possible rendering. Literally, at or in the trespass of (against) Jehovah (lying) upon us, you are proposing to add to our sins, and so on. Others translate, “so that a trespass against Jehovah comes upon us” . But the elders admit an already existing trespass, when they add, for our trespass is great, and there is fierce wrath against Israel. What they deprecate is an aggravation of that trespass.

Our trespass is great. —Literally, a great trespass is ours. (Syriac omits this clause and next verse. Instead of 2 Chronicles 28:15 it has: “And they caused the whole captivity to return to Jerusalem.” It then continues with 2 Chronicles 28:23–25, transposing 2 Chronicles 28:16–21.)
