EDUTH ĕ duth’ (עֵדוּת, H6343, warning, reminder, testimony). Hebrew meaning not found in Eng. VSS. See Testimony.

The eduth refers specifically and collectively to the Ten Commandments (see nodetitle) on the two tablets of stone as the all important and solemn divine charge (Exod 25:16, 21; 31:18; 32:15; 34:29). These were the basic terms of the covenant made by Yahweh as Suzerain with His people. Among modern Jews a man gives his eduth or word that he will perform a certain obligation.

International Standard Bible Encyclopedia (1915)

(`edhuth, "testimony," a technical term for the nodetitle or for the Law):

In Ps 60 title, "set to Shushan Eduth" (literally, "a lily (is) the testimony"); 80 title, "set to Shoshannim Eduth" (literally, "lilies (is) the testimony"). The Hebrew words appear to be intended to designate a melody by the first few words ordinarily associated with it.
