Parashas Vayechi · Passuk 49:13
Zevulun shall dwell at the shore of the sea; and he shall be a shore for ships, and his flank shall be upon Tzidon.
Torah Temimah points to midrashic parallel (R’ Levi on the mother of Yonah).
English: R’ Levi said: From here is a hint that the mother of Yonah the prophet came from Asher, as it is written “and his flank shall be upon Tzidon” — the flank (yerach) from which he issued was from Tzidon.
Remez connecting the tribal boundary to a later prophet’s origin.
There is a midrashic tradition that Yonah’s mother was from the territory associated with Tzidon (linked here to the blessing of Zevulun / Asher).
