Psalms 60:8

“Moab [is] my washpot, etc.] To wash hands and feet in: and so the Syriac version, “and Moab the washing of my feet”; a vessel for low and mean service, and so denotes the servile subjection of the Moabites to David; (see <100802>2 Samuel 8:2); and as the words may be rendered, “the pot of my washing” f813. Great numbers of the Moabites might be at this time servants to the Israelites, and to David and his court particularly; and might be employed, as the Gibeonites were, to be drawers of water, to fill their pots, in which they washed their hands and feet, and their bathing vessels, in which they bathed themselves: Aben Ezra explains it, “I wilt wash their land as a pot;” and so may not only…”

“Moab--is a my washpot--the most ordinary vessel. over--or, "at" Edom--(as a slave) he casts his shoe. Philistia, triumph, &c.--or, rather, "shout." for me--acknowledges subjection (compare Psa 108:9, "over Philistia will I triumph").”

“Moab is my washpot - Moab was a region of country on the east of the Dead Sea, extending as far north as the river Arnon. See the notes at Isaiah 15:1-9. The words rendered wash-pot mean properly a pot or basin for washing, a wash-basin; and the expression is used here as one of contempt, as if he would use it as the meanest vessel is used. It implies that Moab was already subdued, and that the author of the psalm could make any use of it he pleased. It also implies that Moab was not regarded as adding much to his strength, or to the value of his dominions; but that, compared with other portions of his kingdom, it was of as little value as a wash-basin compared with the more valuable vessels…”

“Wash - pot - In which I shall wash my feet. I shall bring them into the lowest degree of servitude. Shoe - I will use them like slaves; a proverbial expression. Triumph - It is an ironical expression, signifying that her triumphs were come to an end. Psalms 60:9”
