V.1-19 The porters were the doorkeepers of the gates of the house of the Lord (v. 12). The doors were guarded continually. This shows us that King David considered this job important as well as the singers work. To get our spiritual teaching from this, we need to realize our own need to be on guard continually. In Ephesians 6:10-1710Finally, my brethren, be strong in the Lord, and in the power of his might. 11Put on the whole armor of God, that ye may be able to stand against the wiles of the devil. 12For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places. 13Wherefore take unto you the whole armor of God, that ye may be able to withstand in the evil day, and having done all, to stand. 14Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness; 15And your feet shod with the preparation of the gospel of peace; 16Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. 17And take the helmet of salvation, and the sword of the Spirit, which is the word of God: (Ephesians 6:10‑17) we read how necessary it is for the believer to have on the whole armor of God. The only other time in Scripture where all the armor is mentioned is in Luke 11:2222But when a stronger than he shall come upon him, and overcome him, he taketh from him all his armor wherein he trusted, and divideth his spoils. (Luke 11:22). That man was overcome. He is a picture of Satan. But the point is that he also was armored (like Goliath, 1 Sam. 17:4-7). But the believers have an armor which cannot be lost if we put it on. God tells us we need to be faithful doorkeepers.
V.29-32 Another group. Those in charge of the outward affairs. A picture of us believers in our contacts each day with people. Three times it describes the type of men needed. Verse 31, they had to look for them, but they found them. Don’t let Satan work on our pride to keep us from telling others about the Lord Jesus Christ.
V.32 For every matter pertaining to God. Everything was of importance.
