How do we know God is a terrible God in the biblical sense?

In Psalm 47:2, the phrase 'the Lord most high is terrible' signifies that God is awe-inspiring and dreadful, referring to His holiness and unmatched power. The Hebrew word translated as 'terrible' suggests an overwhelming sense of reverence and fear in the presence of His majesty. This is echoed in various passages where men encounter God's glory, such as Job's realization of God's omnipotence leading him to repentance (Job 42:5-6). The emphasis is on the understanding that God is not simply a kindly figure; He is the Creator, infinitely greater than His creation, deserving of our utmost reverence.
