Deuteronomy 33:8

Blessing on Levi

8 Of Levi he said:
Your Thummim and Urim ^{▼▼ Thummim and Urim. These terms, whose meaning is uncertain, refer to sacred stones carried in a pouch on the breastplate of the high priest and examined on occasion as a means of ascertaining God’s will or direction. See Exod 28:30; Lev 8:8; Num 27:21; 1 Sam 28:6. See also C. Van Dam, NIDOTTE 1:329–31.} belong to your godly one, ^{▼▼ Heb “godly man.” The reference is probably to Moses as representative of the whole tribe of Levi.}
whose authority you challenged at Massah, ^{▼▼ Massah means “testing” in Hebrew; the name is a wordplay on what took place there. Cf. Exod 17:7; Deut 6:16; 9:22; Ps 95:8–9.}
and with whom you argued at the waters of Meribah. ^{▼▼ Meribah means “contention, argument” in Hebrew; this is another wordplay on the incident that took place there. Cf. Num 20:13, 24; Ps 106:32.}
