Numbers 25:12
לָכֵן אֱמֹר הִנְנִי נֹתֵן לוֹ אֶת בְּרִיתִי שָׁלוֹם
Therefore say, Behold, I give him My covenant of peace.
G-d rewarded Pinchas for his zealousness with a “covenant of peace.” The Targum Yonasan ben Uzziel says that this means immortality, a reference to the Midrash that identifies Pinchas with Eliyahu (the prophet Elijah), who was taken into Heaven alive. (Others do not take the Midrash so literally. For example, ibn Ezra on verse 13 says that Pinchas isn’t Eliyahu at all.)
