Giddal'ti (Heb. id. גַּדִּלתַּי, whom I [Jehovah] have made great; Sept. Γεδδολλαθί and Γεδδελθί, Vulg. Geddelthi and Gedelthi), the ninth named of the four teen musical sons of Heman, and head of the twenty second course of Levitical musicians in the tabernacle under David (1Ch 25:4,29). B.C. 1013. The office of these brothers was to sound the horn in the Levitical orchestra (verse 5, 7). Fürst (who reduces the sons of Heman to five) suggests (Heb. Lex. s.v.) that the appended "names probably formed together (גָּדִלתַי ורֹמִמתֹּי עֶזֶר מִלֹּוֹתַי הוֹתַיר מִחֲזַיאוֹת have dealt out fame and victorious help; I have spoken oracles in fulness) an old prophetic saying with which an oracle began, whose words were applied to the five [as soubriquets]; the tone itself [as a name it would regularly be Giddalti'] pointing to this explanation."
