1 Chronicles 12:38  (King James Version)
All these men of war, that could keep rank, came with a perfect heart to Hebron, to make David king over all Israel: and all the rest also of Israel were of one heart to make David king.

with a perfect heart
The meaning of this expression may be inferred from that of a double heart in ver
33. If a double heart be expressive of insincerity or duplicity, a perfect heart, which seems to be put in opposition to it, must signify a sincere, faithful, and entire attachment.
