Deuteronomy 13:4
Ye shall walk after the Lord your God, and fear him, and keep his commandments, and obey his voice, and ye shall serve him, and cleave unto him. (Deuteronomy 13:4)
His commandments.
 These consist of love expressed in attitudes and actions toward God and man (Lev. 19:18; Deut. 6:5; 10:12; Micah 6:8), as Christ later explained (Matt. 5:43-45; 19:16-22; 22:36-40; see also 1 John 4:6-12).
Ye shall walk.
 This is the basic duty absolutely binding upon each believer (Deut. 6:13; 10:20; 11:13, 22; Eccl. 12:13, 14; Micah 6:8). The Hebrew word order is most emphatic. It would read literally, “after Jehovah your God shall ye walk,” meaning after Him and not after anyone else. Fellowship with God is often spoken of as a “walk” (Gen. 5:24).
