1 Kings 12:22 - Ellicott's Commentary On The Whole Bible

Shemaiah the man of God. — From the notices in 2 Chronicles 12:5-8; 2 Chronicles 12:15, it would seem that, while Ahijah belonged to Shiloh in Ephraim, and continued to dwell there, Shemaiah was rather attached to Judah, and hence, that his interference to protect the new kingdom was the more striking and unexpected. In this interposition, to which probably the very preservation of Jeroboam’s half-formed kingdom was due, there is a fresh indication of the great opportunity given to that kingdom to maintain itself, under the blessing of God and in devotion to His service. The phrase “your brethren, the children of Israel,” marks this with much emphasis.
