Jeremiah 31:34

31:34 “People will no longer need to teach their neighbors and relatives to know me. ¹  For all of them, from the least important to the most important, will know me,” ²  says the Lord. “For ³  I will forgive their sin and will no longer call to mind the wrong they have done.”

Matthew 1:21

1:21 She will give birth to a son and you will name him ⁴  Jesus, ⁵  because he will save his people from their sins.”

Mark 1:4

1:4 In the wilderness ⁶  John the baptizer ⁷  began preaching a baptism of repentance for the forgiveness of sins. ⁸ 

[31:34]  ¹ tn Heb “teach…, saying, ‘Know the Lord.’” The indirect quote has been chosen for stylistic reasons, i.e., to better parallel the following line.

[31:34]  ² sn This statement should be understood against the background of Jer 8:8-9 where class distinctions were drawn and certain people were considered to have more awareness and responsibility for knowing the law and also Jer 5:1-5 and 9:3-9 where the sinfulness of Israel was seen to be universal across these class distinctions and no trust was to be placed in friends, neighbors, or relatives because all without distinction had cast off God’s yoke (i.e., refused to submit themselves to his authority).

[31:34]  ³ tn The Hebrew particle כִּי (ki) that introduces this clause refers to more than just the preceding clause (i.e., that all will know the Lord) but to all of vv. 31-34a (See BDB 474 s.v. כִּי 3.c).

[1:21]  ⁴ tn Grk “you will call his name.”

[1:21]  ⁵ sn The Greek form of the name Ihsous, which was translated into Latin as Jesus, is the same as the Hebrew Yeshua (Joshua), which means “Yahweh saves” (Yahweh is typically rendered as “Lord” in the OT). It was a fairly common name among Jews in 1st century Palestine, as references to a number of people by this name in the LXX and Josephus indicate.

[1:4]  ⁷ tn Or “desert.”

[1:4]  ⁸ tn While Matthew and Luke consistently use the noun βαπτίστης (baptisths, “[the] Baptist”) to refer to John, as a kind of a title, Mark prefers the substantival participle ὁ βαπτίζων (Jo baptizwn, “the one who baptizes, the baptizer”) to describe him (only twice does he use the noun [Mark 6:25; 8:28]).

[1:4]  ⁹ sn A baptism of repentance for the forgiveness of sins was a call for preparation for the arrival of the Lord’s salvation. To participate in this baptism was a recognition of the need for God’s forgiveness with a sense that one needed to live differently as a response to it.
