Why does it say "Asher Akim Lahem"?
1.
Radak #1: Perhaps this refers to David. Hashem will lift him from his earth at the time of Techiyas ha'Mesim.
2.
Radak #2: Perhaps it refers to Mashi'ach, the son of David (many generations later).
3.
Malbim: They will have a king from Beis David. I explained that had Yisrael served Hashem in Bayis Sheni, the final redemption would have been then. Through Aveiros, it was delayed until the Ketz (deadline).
