First Reading: Jeremiah 2:1-3, 7-8, 12-13
1The word of the LORD came to me, saying, 2″Go and proclaim in the hearing of Jerusalem, Thus says the LORD, I remember the devotion of your youth, your love as a bride, how you followed me in the wilderness, in a land not sown. 3Israel was holy to the LORD, the first fruits of his harvest. All who ate of it became guilty; evil came upon them, says the LORD.” 7And I brought you into a plentiful land to enjoy its fruits and its good things. But when you came in you defiled my land, and made my heritage an abomination. 8The priests did not say, `Where is the LORD?’ Those who handle the law did not know me; the rulers transgressed against me; the prophets prophesied by Ba’al, and went after things that do not profit. 12Be appalled, O heavens, at this, be shocked, be utterly desolate, says the LORD, 13for my people have committed two evils: they have forsaken me, the fountain of living waters, and hewed out cisterns for themselves, broken cisterns, that can hold no water.
Responsorial Psalm: Psalms 36:6-11
5Thy steadfast love, O LORD, extends to the heavens, thy faithfulness to the clouds. 6Thy righteousness is like the mountains of God, thy judgments are like the great deep; man and beast thou savest, O LORD. 7How precious is thy steadfast love, O God! The children of men take refuge in the shadow of thy wings. 8They feast on the abundance of thy house, and thou givest them drink from the river of thy delights. 9For with thee is the fountain of life; in thy light do we see light. 10O continue thy steadfast love to those who know thee, and thy salvation to the upright of heart!
Gospel: Matthew 13:10-17
10Then the disciples came and said to him, “Why do you speak to them in parables?” 11And he answered them, “To you it has been given to know the secrets of the kingdom of heaven, but to them it has not been given. 12For to him who has will more be given, and he will have abundance; but from him who has not, even what he has will be taken away. 13This is why I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand. 14With them indeed is fulfilled the prophecy of Isaiah which says: `You shall indeed hear but never understand, and you shall indeed see but never perceive. 15For this people’s heart has grown dull, and their ears are heavy of hearing, and their eyes they have closed, lest they should perceive with their eyes, and hear with their ears, and understand with their heart, and turn for me to heal them.’ 16But blessed are your eyes, for they see, and your ears, for they hear. 17Truly, I say to you, many prophets and righteous men longed to see what you see, and did not see it, and to hear what you hear, and did not hear it.
