Exo_30:19 For Aaron and his sons shall wash their hands and their feet thereat:
Ver. 19. For Aaron and his sons.] Here they were to wash before they prayed for the people. {Heb_10:22} We must first make our own peace with God before we take upon us to intercede for others. So did David. {Psa_25:22; Psa_51:18-19} So we are advised to do, Lam_3:39-40.
