First Reading: Jeremiah 15: 10, 16-21
10 Woe is me, my mother: why hast thou borne me a man of strife, a man of contention to all the earth? I have not lent on usury, neither hath any man lent to me on usury: yet all curse me.
16 Thy words were found, and I did eat them, and thy word was to me a joy and gladness of my heart: for thy name is called upon me, O Lord God of hosts.
17 I sat not in the assembly of jesters, nor did I make a boast of the presence of thy hand: I sat alone, because thou hast filled me with threats.
18 Why is my sorrow become perpetual, and my wound desperate so as to refuse to be healed? it is become to me as the falsehood of deceitful waters that cannot be trusted.
19 Therefore thus saith the Lord: If thou wilt be converted, I will convert thee, and thou shalt stand before my face; and if thou wilt separate the precious from the vile, thou shalt be as my mouth: they shall be turned to thee, and thou shalt not be turned to them.
20 And I will make thee to this people as a strong wall of brass: and they shall fight against thee, and shall not prevail: for I am with thee to save thee, and to deliver thee, saith the Lord.
21 And I will deliver thee out of the hand of the wicked, and I will redeem thee out of the hand of the mighty.
Responsorial Psalm: Psalms 59: 2-3, 4, 10-11, 17, 18
2 Deliver me from my enemies, O my God; and defend me from them that rise up against me.
3 Deliver me from them that work iniquity, and save me from bloody men.
4 For behold they have caught my soul: the mighty have rushed in upon me:
10 I will keep my strength to thee: for thou art my protector:
11 My God, his mercy shall prevent me.
17 But I will sing thy strength: and will extol thy mercy in the morning. For thou art become my support, and my refuge, in the day of my trouble.
18 Unto thee, O my helper, will I sing, for thou art God my defence: my God my mercy.
Gospel: Matthew 13: 44-46
44 The kingdom of heaven is like unto a treasure hidden in a field. Which a man having found, hid it, and for joy thereof goeth, and selleth all that he hath, and buyeth that field.
45 Again the kingdom of heaven is like to a merchant seeking good pearls.
46 Who when he had found one pearl of great price, went his way, and sold all that he had, and bought it.
