"Gather my saints together unto me, those that have made a covenant with me by sacrifice." (Psalm 50:5).
"Now we beseech you, brethren, touching the coming of our Lord Jesus Christ, and our gathering together unto him" (2 Thess. 2:1).
"Not forsaking our own assembling together, as the custom of some is, but exhorting one another; and so much the more, as ye see the day drawing nigh" (Hebrews 10:25).
In all of the above passages there is this one common factor, that an end-time movement and feature is dominant. It must be remembered that the Psalms themselves represent what remains when a history of outward things as to the general instrumentality has ended in failure. The history of Israel in its first great phase closed with the book of "Kings" in a calamitous and shameful way. Weakness, paralysis, declension, reproach, characterized the instrument in general. But out of that history now so concluded the Psalms are carried forward, and they represent what has spiritually been gained and is permanent. This is pre-eminently a personal, inward, spiritual knowledge of the Lord gained through experience.
That is why they always reach the heart and never fail to touch experience at every point. To them the saints have turned in times of deep experience. They are the ministry of experience to experience, the only ministry which is permanent. The end-time instrument will always be that which inwardly knows the Lord in a deep and living way through history fraught with much experience of the heights and depths. What David gave to the Chief Musician for the wind instruments and the stringed instruments touches the highest and deepest notes of a mortal's knowledge of God. Worship, Salvation, Sorrow, Appeal, Victory, Battle, Faith, Hope, Glory, Instruction, are all great themes interwoven with the mass of matters touched, but the point is that all came in real life; he passed through it all. It is this, and this alone, which can serve the Lord when what He first raised up has failed Him as a public instrument. So the Lord would take pains to secure this, and this may explain much of the suffering and sorrow through which He takes His chosen vessels.
It does not need pointing out that, in the other two passages with which we commenced, the end-time is in view; they definitely state it.
There is a further common feature, however, which is more particularly the subject before us. They all definitely refer to gathering together as something related to the end-time. The Day is drawing nigh, therefore there is to be a "so much the more" assembling together. The Lord is coming, and there is a gathering to Him.
A history of a religious system which sprang out of something which the Lord raised up in the first place has ended in weakness, chaos and shame. Therefore, there is to be a re-gathering to the Lord of His saints.
Before we deal with the nature of this end-time gathering, we must get clearly in view those that are concerned in it. The passage in the Psalm would embrace and include those referred to in the other two passages.
