Job 29:6

“When I washed my steps with butter, etc.] Not the steps of his house or palace; for to have done this, or his servants by his orders, as it would have been a very great impropriety, so a piece of great prodigality, which Job could never have been guilty of; but either his footsteps, the prints of his feet; and the sense be, that his cattle produced such a vast quantity of milk, that when his servants brought it from the fields to the dairy, their milk pails ran over in such abundance, that Job could not step out of his house, and take a walk in his fields, but he stepped into puddles of milk, of which butter was made: this is an exaggerated phrase, like that by which the land of Canaan is…”

“butter--rather, "cream," literally, "thick milk." Wherever I turned my steps, the richest milk and oil flowed in to me abundantly. Image from pastoral life. When I washed my steps--Literal washing of the feet in milk is not meant, as the second clause shows; Margin, "with me," that is, "near" my path, wherever I walked (Deu 32:13). Olives amidst rocks yield the best oil. Oil in the East is used for food, light, anointing, and medicine.”

“When I washed my steps with butter - On the word rendered “butter,” see the notes at Isaiah 7:15. It properly means curdled milk. Umbreit renders it, Sahne; cream. Noyes, milk, and so Wemyss. The Septuagint, “When my ways flowed with butter” - βουτύρῳ bouturō. So Coverdale, “When my ways ran over with butter.” Herder, “And where I went a stream of milk flowed on.” The sense may be, that cream or butter was so plenty that he was able to make use of it for the most common purposes - even for that of washing his feet. That butter was sometimes used for the purpose of anointing the feet - probably for comfort and health - as oil was for the head, is mentioned by Oriental travelers.…”

“I washed: Job 20:17; Gen 49:11; Deu 32:13, Deu 33:24; Psa 81:16 me out: Heb. with me Job 29:7”
