Albert Barnes Commentary Leviticus 19:35-36

"Ye shall do no unrighteousness in judgment, in measures of length, of weight, or of quantity. Just balances, just weights, a just ephah, and a just hin, shall ye have: I am Jehovah your God, who brought you out of the land of Egypt." — Leviticus 19:35-36 (ASV)

The ephah is here considered the standard of dry measure, and the hin (see Exodus 29:40 note) as the standard of liquid measure. Of the two very different estimates of the capacities of these measures, the more probable one is that the ephah held not quite four and a half gallons, and the hin not quite six pints. The log was a twelfth part of the hin (Leviticus 14:10).

I am the Lord your God... (Leviticus 19:36). A full stop should precede these words. They introduce the formal conclusion to the whole string of precepts in this chapter, which are all enforced based on the nation's election by Yahweh, who had delivered them from bondage in Egypt.
