לֹֽא־יָס֥וּר שֵׁ֙בֶט֙ מִֽיהוּדָ֔ה וּמְחֹקֵ֖ק מִבֵּ֣ין רַגְלָ֑יו עַ֚ד כִּֽי־יָבֹ֣א שילה [שִׁיל֔וֹ] וְל֖וֹ יִקְּהַ֥ת עַמִּֽים׃
The sceptre shall not depart from Judah, Nor the ruler’s staff from between his feet, As long as men come to Shiloh; And unto him shall the obedience of the peoples be.
Zohar
Another explanation of the phrase: "plant of the field" is the first Messiah, (Mashiach ben David) who was not yet on earth, whereas "herb of the field" is the second Messiah, (Mashiach ben Yosef) Why? Because Moses was not there with them to serve the Shechinah. Of him, it is written: "And there was not a man to till the ground." The secret is given in the verse: "The staff shall not depart from Judah..." (Beresheet 49:10), which refers to Messiah ben David, "nor the scepter from between his feet," which refers to Messiah ben Joseph. "Until Shiloh come" is an allusion to Moses, as the numerical value of (Moshe) is the same as that (Shiloh). "And the obedience of the people be his (Heb. velo yik'hat)"
