פּירוש אויף דברים 33:28

בטח בדד [THEREFORE ISRAEL DWELT] IN SAFETY, ALONE — This means, every individual dwelling “each under his vine and under his fig-treeבטח) ״; cf. 1 Kings 5:5 where the words Rashi quotes are preceded by לבטח), separated one from another (בדד, “alone”), because after the enemy was driven out, as stated in the preceding verse, they had no need to come together and to dwell in company on account of the enemy.

עין יעקב, “the fountain of Yaakov;” a metaphor for the descendants of Yaakov, as in Isaiah 48,1: וממי יהודה יצאו, “and who came forth from the waters of Yehudah.” (metaphor for “from the loins of”)

the fountain of Jacob all those who issued forth from the stream of Jacob. Compare, “who came forth from the waters of Y e hudah” [Isaiah 48: 1].

עין יעקב — The word עין has the same meaning here as in (Numbers 11:7) “And its appearance (עינו) was as the appearance (עין) of crystal” (i.e., the word עין is used as a term of comparison, “as”, ”like”). The meaning is: And Israel dwelt alone like the blessing with which Jacob blessed them (cf. Targum); not like the בדד which Jeremiah used, (Jeremiah 15:17), viz., “I sat alone (בדד) [because of thy hand, for thou hast filled me with Thy indignation]”, but like the assurance which Jacob gave them, (Genesis 48:20) “And God shall be with you, and bring you back to the land of your fathers” (cf. Sifrei Devarim 356:6).
