4:23-31 Christ's followers do best in company, provided it is their own company. It encourages God's servants, both in doing work, and suffering work, that they serve the God who made all things, and therefore has the disposal of all events; and the Scriptures must be fulfilled. Jesus was anointed to be a Saviour, therefore it was determined he should be a sacrifice, to make atonement for sin. But sin is not the less evil for God's bringing good out of it. In threatening times, our care should not be so much that troubles may be prevented, as that we may go on with cheerfulness and courage in our work and duty. They do not pray, Lord let us go away from our work, now that it is become dangerous, but, Lord, give us thy grace to go on stedfastly in our work, and not to fear the face of man. Those who desire Divine aid and encouragement, may depend upon having them, and they ought to go forth, and go on, in the strength of the Lord God. God gave a sign of acceptance of their prayers. The place was shaken, that their faith might be established and unshaken. God gave them greater degrees of his Spirit; and they were all filled with the Holy Ghost, more than ever; by which they were not only encouraged, but enabled to speak the word of God with boldness. When they find the Lord God help them by his Spirit, they know they shall not be confounded, Isa 1.7.
25. by the mouth of … David—to whom the Jews ascribed the second Psalm, though anonymous; and internal evidence confirms it. David's spirit sees with astonishment "the heathen, the people, the kings and princes of the earth," in deadly combination against the sway of Jehovah and His Anointed (his Messiah, or Christ), and asks "why" it is. This fierce confederacy our praying disciples see in full operation, in the "gathering together of Herod and Pilate, the Gentiles (the Roman authority), and the people of Israel, against God's holy Child ('Servant') Jesus." (See on Ac 3:13). The best ancient copies read, after "were gathered together," "in this city," which probably answers to "upon my holy hill of Zion," in the Ps 2:6.
