10Finally, be strong in the Lord and in the strength of his might. 11Put on the whole armor of God, that you may be able to stand against the wiles of the devil. 12For we are not contending against flesh and blood, but against the principalities, against the powers, against the world rulers of this present darkness, against the spiritual hosts of wickedness in the heavenly places. 13Therefore take the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand. 14Stand therefore, having girded your loins with truth, and having put on the breastplate of righteousness, 15and having shod your feet with the equipment of the gospel of peace; 16besides all these, taking the shield of faith, with which you can quench all the flaming darts of the evil one. 17And take the helmet of salvation, and the sword of the Spirit, which is the word of God. 18Pray at all times in the Spirit, with all prayer and supplication. To that end keep alert with all perseverance, making supplication for all the saints, 19and also for me, that utterance may be given me in opening my mouth boldly to proclaim the mystery of the gospel, 20for which I am an ambassador in chains; that I may declare it boldly, as I ought to speak.

Responsorial Psalm Psalms 144:1-2, 9-10

1Blessed be the LORD, my rock, who trains my hands for war, and my fingers for battle; 2my rock and my fortress, my stronghold and my deliverer, my shield and he in whom I take refuge, who subdues the peoples under him. 9I will sing a new song to thee, O God; upon a ten-stringed harp I will play to thee, 10who givest victory to kings, who rescuest David thy servant.

Gospel Luke 13:31-35

31At that very hour some Pharisees came, and said to him, "Get away from here, for Herod wants to kill you." 32And he said to them, "Go and tell that fox, `Behold, I cast out demons and perform cures today and tomorrow, and the third day I finish my course. 33Nevertheless I must go on my way today and tomorrow and the day following; for it cannot be that a prophet should perish away from Jerusalem.' 34O Jerusalem, Jerusalem, killing the prophets and stoning those who are sent to you! How often would I have gathered your children together as a hen gathers her brood under her wings, and you would not! 35Behold, your house is forsaken. And I tell you, you will not see me until you say, `Blessed is he who comes in the name of the Lord!'"
