Forms
δῐᾰθήκη (diathḗkē) f (genitive δῐᾰθήκης); first declension[1]
Etymology
It is a noun from Ancient Greek διατίθημι (diatíthēmi, “to arrange, dispose of”).[2][3][1][4] It can also be analysed as δια- (dia-) and -θήκη (-thḗkē),[1] but BDAG says its meaning must be explained from the middle διατίθεμαι (diatíthemai), used in legal and commercial language for disposing of property, not from the simple θήκη (thḗkē, “case, chest”).[5]
Earliest recorded meaning
Democritus uses it for the disposition or state of the body.[3][2][6] In Aristophanes it already means both a will and a compact.[2][3]
Semantic evolution
In Attic law it was a will: Plato and Isaeus speak of making and writing one, and the orators of property left “according to the will”.[6][2] Dinarchus mentions secret deposits on which the safety of the city depended, probably oracles.[2][3] A physician's eyesalve was called by this name because its recipe had been deposited in a temple.[2] In Hellenistic Greek outside the Bible it means only a last will.[5]
The Septuagint uses it almost always for Hebrew בְּרִית (bərīṯ) “covenant”.[7] BDAG explains the choice: the word kept the idea of a legal disposition made by one party alone, without the death of the testator, so a covenant of God was a decree whose terms God alone set.[5] The New Testament speaks of a new and an old covenant, and Galatians and Hebrews play on the two senses of covenant and will.[2][5] Babiniotis notes that the phrases “Old” and “New Testament” first had this biblical sense.[4] Coptic borrowed the word, and it is recorded there from about AD 600.[8]
In Modern Greek διαθήκη (diathíki) is a learned word: “will” continues the ancient sense, and “covenant” and the names of the two Testaments the Hellenistic one.[9]
