Leviticus 19:5 - Joseph Benson’s Commentary on the Old and New Testaments

At your own will Or, According to your own pleasure, what you think fit; for though this sacrifice, in general, was required, it was left to their choice to determine the particulars. But the original word may be rendered, For favour to you; that is, in order to procure you the divine favour; or in such a manner as God has prescribed and will accept. And thus it is understood by Le Clerc, after the LXX., the Vulgate, Syriac, and Arabic versions.
