Laban never quite gave the impression that he really knew God.
It’s not just that he was greedy and worried about his wealth, although greed does seem to feature in the less admirable characters such as Lot and Laban.
It’s also his mixing up of God and ‘unGod’, for example:
Genesis 30:27 I have learned by divination that the Lord has blessed me because of you.
Although Laban called God ‘The Lord’, he still had his household idols and he was happy to engage in the occult.
By the time Moses gave the law to the Israelites, divination was banned, for example:
Leviticus 19:26 Do not practice divination or seek omens.
And it was later identified as one of the detestable practices of the people living in Canaan:
Deuteronomy 18:9–13 When you enter the land the Lord your God is giving you, do not learn to imitate the detestable ways of the nations there. Let no one be found among you … who practices divination or sorcery… Anyone who does these things is detestable to the Lord; because of these same detestable practices the Lord your God will drive out those nations before you. You must be blameless before the Lord your God.
It wasn’t acceptable to mix up holiness with unholy activities, such as consulting with demons through divination and other occult practices.
Nevertheless, Balaam tried it, without getting the response he was looking for.
So the answer would have to be ‘no’: divination is not acceptable for God’s people.
