Archaic third-person singular present tense of 'conve,' meaning to come together or assemble.
From Old English and Middle English 'comen' variants or rare verbs. An obsolete form from Early Modern English Biblical and literary translation, following the archaic -eth conjugation pattern.
The -eth ending (he conveth, she loveth, it falleth) dominated English until about 1700, when -s endings took over. You see -eth in the King James Bible constantly, which is why Shakespeare's English looks so different from modern speech.
