Isaiah 11:1-10 New Revised Standard Version (NRSV)
The Peaceful Kingdom
11 A shoot shall come out from the stump of Jesse,
He shall not judge by what his eyes see,
6 The wolf shall live with the lamb,
Return of the Remnant of Israel and Judah
10 On that day the root of Jesse shall stand as a signal to the peoples; the nations shall inquire of him, and his dwelling shall be glorious.
Romans 15:4-13 New Revised Standard Version (NRSV)
4 For whatever was written in former days was written for our instruction, so that by steadfastness and by the encouragement of the scriptures we might have hope. 5 May the God of steadfastness and encouragement grant you to live in harmony with one another, in accordance with Christ Jesus, 6 so that together you may with one voice glorify the God and Father of our Lord Jesus Christ.
The Gospel for Jews and Gentiles Alike
7 Welcome one another, therefore, just as Christ has welcomed you, for the glory of God. 8 For I tell you that Christ has become a servant of the circumcised on behalf of the truth of God in order that he might confirm the promises given to the patriarchs, 9 and in order that the Gentiles might glorify God for his mercy. As it is written,
“Therefore I will confess[a] you among the Gentiles,
10 and again he says,
“Rejoice, O Gentiles, with his people”;
11 and again,
“Praise the Lord, all you Gentiles,
12 and again Isaiah says,
“The root of Jesse shall come,
13 May the God of hope fill you with all joy and peace in believing, so that you may abound in hope by the power of the Holy Spirit.
Matthew 3:1-12 New Revised Standard Version (NRSV)
The Proclamation of John the Baptist
3 In those days John the Baptist appeared in the wilderness of Judea, proclaiming, 2 “Repent, for the kingdom of heaven has come near.”[a] 3 This is the one of whom the prophet Isaiah spoke when he said,
“The voice of one crying out in the wilderness:
4 Now John wore clothing of camel’s hair with a leather belt around his waist, and his food was locusts and wild honey. 5 Then the people of Jerusalem and all Judea were going out to him, and all the region along the Jordan, 6 and they were baptized by him in the river Jordan, confessing their sins.
7 But when he saw many Pharisees and Sadducees coming for baptism, he said to them, “You brood of vipers! Who warned you to flee from the wrath to come? 8 Bear fruit worthy of repentance. 9 Do not presume to say to yourselves, ‘We have Abraham as our ancestor’; for I tell you, God is able from these stones to raise up children to Abraham. 10 Even now the ax is lying at the root of the trees; every tree therefore that does not bear good fruit is cut down and thrown into the fire.
11 “I baptize you with[b] water for repentance, but one who is more powerful than I is coming after me; I am not worthy to carry his sandals. He will baptize you with[c] the Holy Spirit and fire. 12 His winnowing fork is in his hand, and he will clear his threshing floor and will gather his wheat into the granary; but the chaff he will burn with unquenchable fire.”
