PS 19:2-3, 4-5
22Then it seemed good to the apostles and the elders, with the whole church, to choose men from among them and send them to Antioch with Paul and Barnabas. They sent Judas called Barsab'bas, and Silas, leading men among the brethren, 23with the following letter: "The brethren, both the apostles and the elders, to the brethren who are of the Gentiles in Antioch and Syria and Cili'cia, greeting. 24Since we have heard that some persons from us have troubled you with words, unsettling your minds, although we gave them no instructions, 25it has seemed good to us, having come to one accord, to choose men and send them to you with our beloved Barnabas and Paul, 26men who have risked their lives for the sake of our Lord Jesus Christ. 27We have therefore sent Judas and Silas, who themselves will tell you the same things by word of mouth. 28For it has seemed good to the Holy Spirit and to us to lay upon you no greater burden than these necessary things: 29that you abstain from what has been sacrificed to idols and from blood and from what is strangled and from unchastity. If you keep yourselves from these, you will do well. Farewell." 30So when they were sent off, they went down to Antioch; and having gathered the congregation together, they delivered the letter. 31And when they read it, they rejoiced at the exhortation.
Psalms 57:8-10, 12
7My heart is steadfast, O God, my heart is steadfast! I will sing and make melody! 8Awake, my soul! Awake, O harp and lyre! I will awake the dawn! 9I will give thanks to thee, O Lord, among the peoples; I will sing praises to thee among the nations. 11Be exalted, O God, above the heavens! Let thy glory be over all the earth!
12"This is my commandment, that you love one another as I have loved you. 13Greater love has no man than this, that a man lay down his life for his friends. 14You are my friends if you do what I command you. 15No longer do I call you servants, for the servant does not know what his master is doing; but I have called you friends, for all that I have heard from my Father I have made known to you. 16You did not choose me, but I chose you and appointed you that you should go and bear fruit and that your fruit should abide; so that whatever you ask the Father in my name, he may give it to you. 17This I command you, to love one another.
