This rare verbal root expresses the idea of being firm or strong, particularly in the sense of enduring or remaining stable over time. It appears only twice, both times describing things that persist: Job's prosperity that does not endure (negated), and the ways of the wicked that are always firm or prosperous. The multilingual evidence points to prosperity and endurance as the core semantic thread, though the French 'enfanter' (to give birth) suggests some translators saw a connection to labor or travail, possibly confusing this root with the more common חול (to writhe).
