Matthew 5:1 Seeing the crowds, he went up on the mountain, and when he sat down, his disciples came to him. [2] And he opened his mouth and taught them, saying: [3] “Blessed are the poor in spirit, for theirs is the kingdom of heaven. [4] “Blessed are those who mourn, for they shall be comforted. [5] “Blessed are the meek, for they shall inherit the earth. [6] “Blessed are those who hunger and thirst for righteousness, for they shall be satisfied. [7] “Blessed are the merciful, for they shall receive mercy. [8] “Blessed are the pure in heart, for they shall see God. [9] “Blessed are the peacemakers, for they shall be called sons of God. [10] “Blessed are those who are persecuted for righteousness' sake, for theirs is the kingdom of heaven. [11] “Blessed are you when others revile you and persecute you and utter all kinds of evil against you falsely on my account. [12] Rejoice and be glad, for your reward is great in heaven, for so they persecuted the prophets who were before you.
