Pirkei Avot 5:6:
עֲשָׂרָה דְבָרִים נִבְרְאוּ בְעֶרֶב שַׁבָּת בֵּין הַשְּׁמָשׁוֹת, וְאֵלּו הֵן.... וְהַשָּׁמִיר,:
Ten things were created on the eve of the [first] Shabbat at twilight. And these are they: ... the dill
I see that all the other items in the list were used either for some other miracle / event mentioned in the Torah or in the Temple. Point is, that they are mentioned somewhere in Tanac"h. Where was dill mentioned in Tanac"h; What was its use?
