You can trust in man or God (Jer 17:5-8); Moses failed originally by trusting in man to deliver Israel (Act 7:25). Three elements of deliverence: (1) there must be a divine commission - God's order, power and in His way (Exo 4:18-23). Moses starts out right orienting to authority; (2) there must be personal refining (Exo 4:24). The Lord "meets Moses at the inn to kill him" because Moses' bitterness for 40 years (Heb 12:14-15, 1Jo 5:16, Eze 18:31-32); Moses was on the verge of the sin unto death (1Co 5:1-5, Jam 5:19-20, 2Sa 12:13, Psa 118:17-18). God promised Abraham in Gen 15:16 but Moses violated Gen 17:14 - his son was not circumcisized (Exo 4:24); circumcision is a sign or regenerating faith (Rom 4:11); (3) collective unity - the formation of a team (Exo 4:27-31, Luk 10:1)
