Give thee charge concerning Israel, i.e. give thee instructions or direction rightly to manage and rule his people Israel. Or, and set thee over Israel, as the Syriac renders it, whom the Arabic follows. Or, when (as the Hebrew vau is oft used) he shall set thee over Israel, i.e. when thou shalt be king; for then Solomon would need this wisdom, for which therefore he prayeth, 1 Kings 3:9.
