Judges 4:19

Milk, out of a shew of greater civility. The Rabbins say the milk was sour, which is conformable to the manners of the oriental nations. Valle remarks, that the Arabs still give the preference to it. The bottle is which it was kept was made of leather, ( utrem) and the milk was like cream, chap. v. 25. Some think that wine was not then used in this family, as the Rechabites, descendants of the Cinites, always refrained from it, Jeremias xxv. But it is not certain that they did at this time, nor that they sprang from this branch of the family.
