Job 29:6
When I washed my steps with butter, and the rock poured me out rivers of oil;
When I washed my steps with butter,.... 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 described as "flowing with milk and honey"; or rather this is to be understood of the washing of his feet, which are the instruments of stepping or walking. It was usual in those times, in the eastern countries, to wash their feet upon travelling, or at festivals; but then this was commonly done with water, not with butter, see
Genesis 18:4; and the meaning can only be, that Job had such abundance of milk, or butter made of it, that he could, if he would, have washed his feet in it; indeed, they had used to anoint the feet with ointment; but whether cream or butter was any ingredient in it, and so the part is put for the whole, is not certain, see Luke 7:38
