Prokeimenon. Mode Plagal 4 Psalm 18.4,1
Their voice has gone out into all the earth.
Verse: The heavens declare the glory of God.
The reading is from St. Paul's First Letter to the Thessalonians 2:9-14
Brethren, remember our labor and toil; we worked night and day, that we might not burden any of you, while we preached to you the gospel of God. You are witnesses, and God also, how holy and righteous and blameless was our behavior to you believers; for you know how, like a father with his children, we exhorted each one of you and encouraged you and charged you to lead a life worthy of God, who calls you into his own kingdom and glory. And we also thank God constantly for this, that when you received the word of God which you heard from us, you accepted it not as the word of men but as what it really is, the word of God, which is at work in you believers. For you, brethren, became imitators of the churches of God in Christ Jesus which are in Judea.
The Gospel According to Luke 20:9-18
The Lord said this parable: "A man planted a vineyard, and let it out to tenants, and went into another country for a long while. When the time came, he sent a servant to the tenants, that they should give him some of the fruit of the vineyard; but the tenants beat him, and sent him away empty-handed. And he sent another servant; him also they beat and treated shamefully, and sent him away empty-handed. And he sent yet a third; this one they wounded and cast out. Then the owner of the vineyard said, 'What shall I do? I will send my beloved son; it may be they will respect him.' But when the tenants saw him, they said to themselves, 'This is the heir; let us kill him, that the inheritance may be ours.' And they cast him out of the vineyard and killed him. What then will the owner of the vineyard do to them? He will come and destroy those tenants, and give the vineyard to others." When they heard this, they said, "God forbid!" But he looked at them and said, "What then is this that is written: 'The very stone which the builders rejected has become the head of the corner'? Every one who falls on that stone will be broken to pieces; but when it falls on any one it will crush him."
