The Hebrew noun miqnah (מִקְנָה) refers to something purchased, acquired, or bought — particularly a possession obtained through financial transaction. It appears about 15 times in the Old Testament, most prominently in the context of land redemption, slave purchases, and the laws governing bought property.
The theology of miqnah is inseparable from the theme of redemption. In Leviticus and Ruth, the right of redemption (geullah) often involves a miqnah — a purchase that restores what was lost. Jeremiah dramatically purchased (qanah) a field as a sign that God would restore Israel's fortunes (Jeremiah 32), making a legal miqnah into a prophetic act. Every purchased possession in Israel was ultimately a stewardship — the land belonged to God. This foreshadows the New Testament theme of redemption: believers are 'bought with a price' (1 Corinthians 6:20), a divine miqnah that establishes God's ownership and our belonging.
