1: ἀγοράζω
(Strong's #59 — Verb — agorazo — ag-or-ad'-zo )

primarily, "to frequent the market-place," the agora, hence "to do business there, to buy or sell," is used lit., e.g., in Matthew 14:15 . Figuratively Christ is spoken of as having bought His redeemed, making them His property at the price of His blood (i.e., His death through the shedding of His blood in expiation for their sins), 1—Corinthians 6:20; 7:23; 2—Peter 2:1; see also Revelation 5:9; 14:3,4 (not as AV, "redeemed"). Agorazo does not mean "to redeem." See REDEEM.

2: ὠνέομαι
(Strong's #5608 — Verb — oneomai — o-neh'-om-ahee )

"to buy, in contradistinction to selling," is used in Acts 7:16 , of the purchase by Abraham of a burying place.

James 4:13 2—Peter 2:3MERCHANDISE.
