Pensamiento judío sobre Jeremías 31:6

(Song 4:16) “North, wake up; South, come” -- In gematria, the initial letters of the words: equal [566] Mashiach ben Yosef who first awakens in the North. As it states in the Midrash: The mashiach is in the North. Therefore the beginning of the ingathering of the exiles is from the land of the north, as is written: “behold, I will bring them from the land of the North” (Jer. 31:7). In the same chapter we find: “Efraim is My firstborn, ” and “call out on Mount Efraim, ’Rise and let us go up to Zion’” (Jer. 31: 5) etc., as explained above (#1), in the discussion of the aspect “Efraim is My firstborn.”

(Jer. 31:5) “rise and let us ascend to Zion” -- This refers to Efraim who is Mashiach ben Yosef through whom the ingathering of exiles will be accomplished. See above (#1), on the aspect “Efraim is My firstborn.” As known, wherever the term is used, it is in line with Yosef, like the reference: “my sheaf rose.”

R’ Yehoshua says ‘one who is traveling in a dangerous place should offer a brief prayer and say ‘save, G–d, your people - the remnant Israel’. (Yermiyahu 31:6) [Mishna Berachot 4:4]
Since for the complete acceptance of prayer, through the lofty status of joining one’s soul together with the community, it is fitting as much as possible to make one’s state equivalent to that of the community, when one is in a place of danger they should recall that all the remnant of Israel likewise need G–d’s salvation, because they too are in a place of danger, “one lamb among seventy wolves.” (See Tanchuma Toldot 5) And in the salvation of the whole, the individual is saved as well.
