Enchantment, נָחַשׁ. Rather, "augury." Septuagint, οἰωνισμός. See on Le 19:26, where the practice is forbidden to Israel. Against Jacob, or, "in Jacob," as the marginal reading, and this is favoured by the Septuagint and the Targums, and is equally true and striking.
It was the proud peculiarity of Israel that he trusted not to any magic arts or superstitious rites, uncertain in themselves, and always leading to imposture, but to the direction and favour of the Almighty.
Divination. קֶסֶם. Septuagint, μαντεία. The art of the soothsayer. According to this time it shall be said of Jacob and of Israel. Rather, "in season," i.e; in God's good time, "it shall be said to Jacob and to Israel.
What hath God wrought! or, "what God doeth." The meaning seems to be that augury and divination were useless and vain in the case of Israel, because God himself declared and would declare his mighty acts in behalf of his people, and that by no uncertain vaticination, but by open declaration.
