Qanah means to acquire, buy, purchase, or create. It appears about 85 times. It covers commercial transactions and, significantly, God's possession/creation of heaven and earth.
God is called 'Creator [qoneh] of heaven and earth' (Genesis 14:19). The word bridges creation and ownership — what God made, He owns. Israel is His possession, acquired through redemption. The verb also describes wisdom as something to be acquired at any cost.
