Leviticus 20:7

Exhortation to Holiness and Obedience

20:7 “‘You must sanctify yourselves and be holy, because I am the Lord your God.

Amos 3:3

3:3 Do two walk together without having met? ¹ 

[3:3]  ¹ sn The rhetorical questions in vv. 3-5 expect the answer, “No, of course not!” Those in v. 6 anticipate the answer, “Yes, of course they do/he is.” They all draw attention to the principle of cause and effect and lay the logical foundation for the argument in vv. 7-8. Also note the progression from a general question in v. 3 to the “meetings” of two animals (v. 4), to that of an animal and a human trap (v. 5), to a climax with the confrontation with the Lord (v. 6). Each of these meetings is disastrous.
