The Hebrew word seeph describes a divided mind or wavering, branching thoughts — pulled in multiple directions at once. It comes from a root meaning to branch off or divide, like a forking path. Seeph is the opposite of singleness of heart; it is the divided soul torn between competing loyalties.
Psalm 119:113: 'I hate double-minded people (seephim), but I love your law.' The psalmist contrasts divided-mindedness with wholehearted devotion. This anticipates James 1:8 — 'a double-minded man is unstable in all he does' — and Elijah's challenge on Carmel: 'How long will you waver between two opinions?' (1 Kings 18:21).
