KJV:
For the eyes of the LORD run to and fro throughout the whole earth, to shew himself strong in the behalf of them whose heart is perfect toward him. Herein thou hast done foolishly: therefore from henceforth thou shalt have wars.
NASB:
"For the eyes of the LORD move to and fro throughout the earth that He may strongly support those whose heart is completely His. You have acted foolishly in this. Indeed, from now on you will surely have wars."
