Derek means way, road, path, journey, or manner of life. Appearing over 700 times, it describes both physical roads and metaphorical life paths. The 'way of the LORD' is a key ethical concept throughout Scripture.
The metaphor of two ways — the way of the righteous and the way of the wicked — structures much of biblical ethics. God's derek represents His character and will; walking in God's ways means living according to His commands. Jesus declares 'I am the Way,' fulfilling this rich concept.
