Numbers 15:39

You must have this tassel so that you may look at it and remember all the commandments of the Lord and obey them and so that you do not follow ¹  after your own heart and your own eyes that lead you to unfaithfulness. ² 

Ex 13:9; Ex 34:15,16; De 6:6-9; De 11:18-21,28-32; De 29:19; Job 31:7; Ps 73:27; Ps 106:39; Pr 3:1; Pr 28:26; Ec 11:9; Jer 9:14; Eze 6:9; Ho 2:2; Jas 4:4

¹ tn Heb “seek out, look into.”

² tn This last clause is a relative clause explaining the influence of the human heart and physical sight. It literally says, “which you go whoring after them.” The verb for “whoring” may be interpreted to mean “act unfaithfully.” So, the idea is these influences lead to unfaithful activity: “after which you act unfaithfully.”
