From agora; properly, to go to market, i.e. (by implication) to purchase; specially, to redeem -- buy, redeem.
see GREEK agora
1. to frequent the marketplace.
2. to buy (properly, in the marketplace) (Aristophanes, Xenophon, others); used
a. literally: absolutely, Matthew 21:12; Mark 11:15; Luke 19:45 (not G T Tr WH); τί, Matthew 13:44, 46; Matthew 14:15 and parallel passage, John 4:8; John 6:5; with παρά and the genitive of the person from whom, Revelation 3:18 (the Sept., Polybius); ἐκ and the genitive of price, Matthew 27:7; simple genitive of price, Mark 6:37.
b. figuratively: Christ is said to have purchased his disciples i. e. made them, as it were, his private property, 1 Corinthians 6:20 (this is commonly understood of God; but cf. John 17:9, 10); 1 Corinthians 7:23 (with the genitive of price added; see τιμή, 1); 2 Peter 2:1. He is also said to have bought them for God ἐν τῷ αἵματι αὐτοῦ, by shedding his blood, Revelation 5:9; they, too, are spoken of as purchased ἀπό τῆς γῆς, Revelation 14:3, and ἀπό τῶν ἀνθρώπων, Revelation 14:4, so that they are withdrawn from the earth (and its miseries) and from (wicked) men. But ἀγοράζω does not mean redeem (ἐξαγοράζω) — as is commonly said. (Compare: ἐξαγοράζω.)
