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 6:10-17 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 11:22. 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.20-28 Next, were the men in charge of the treasures. We believers have received “treasures” too (Col. 2:2-3). The world has its treasures, but they are not worthy to be compared with our treasures in Christ (Heb. 11:26).
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.
