'Walk in the Ways of' in the Bible

who forsake the paths of uprightness, to walk in the ways of darkness;

Rejoice, young man, in your youth, and let your heart cheer you in the days of your youth, and walk in the ways of your heart, and in the sight of your eyes; but know that for all these things God will bring you into judgment.

for you are still fleshly. For insofar as there is jealousy, strife, and factions among you, are you not fleshly, and do you not walk in the ways of men?
