A rich word for potent strength — the strength that provides security and enables victory. Oz can describe the physical might of warriors or animals, the military strength of fortifications, and supremely the incomparable power of God that sustains and delivers his people.
The Psalms celebrate God as the oz of Israel: 'The LORD is my strength and my song' (Ps 118:14). This is not abstract theology but personal experience — God's power exercised on behalf of the weak. The magnificent Psalm 29 thunders 'the LORD will give oz to his people' as its climax. In the Psalter, to praise God's oz is to declare that his power is available to those who trust him.
