Adam Clarke on 2 Chronicles 22:10

All the seed royal of the house of Judah - Nothing but the miraculous intervention of the Divine providence could have saved the line of David at this time, and preserved the prophecy relative to the Messiah. The whole truth of that prophecy, and the salvation of the world, appeared to be now suspended on the brittle thread of the life of an infant of a year old, (see 2Chr 24:1), to destroy whom was the interest of the reigning power! But God can save by few as well as by many. He had purposed, and vain were the counter-exertions of earth and hell.
