covenant (n.)

c. 1300, from Old French covenant "agreement," originally present participle of covenir "agree, meet," from Latin convenire "come together, unite; be suitable, agree," from com- "together" (see com-) + venire "to come," from a suffixed form of PIE root *gwa- "to go, come." Applied in Scripture to God's arrangements with man as a translation of Latin testamentum, Greek diatheke, both rendering Hebrew berith (though testament also is used for the same word in different places).

covenant (v.)

c. 1300, from covenant (n.). Related: Covenanted; covenanting. Covenanter (1638) was used especially in reference to Scottish Presbyterians who signed the Solemn League and Covenant (1643) for the defense and furtherance of their cause.
