Concise Bible Dictionary:
This word is not used in scripture in the sense of familiar discourse. It occurs in the Old Testament in Psalm 37:14 and Psalm 50:23, and refers to the walk; it reads in the margin “the upright of way,” that “disposeth his way.” In the New Testament the word ἀναστροθή has a similar sense of “walk, conduct, behavior” (Gal. 1:13; Eph. 4:22; 1 Tim. 4:12); and in all other passages except Philippians 1:27; and Philippians 3:20 (where it is πολίτευμα, “citizenship” which for the Christian is in heaven, separating him from citizenship on earth and its politics); and Hebrews 13:5, τρόπος, “general manner of life.”
