'Staff' in the Bible

I am unworthy of all the lovingkindness and compassion and of all the faithfulness which You have shown to Your servant. With only my staff [long ago] I crossed over this Jordan, and now I have become [blessed and increased into these] two groups [of people].

He said, “What pledge shall I give you?” She said, “Your seal and your cord, and the staff that is in your hand.” So he gave them to her and was intimate with her, and she conceived by him.

While she was being brought out, she [took the things Judah had given her and] sent [them along with a message] to her father-in-law, saying, “I am with child by the man to whom these articles belong.” And she added, “Please examine [them carefully] and see [clearly] to whom these things belong, the seal and the cord and staff.”

“The scepter [of royalty] shall not depart from Judah,Nor the ruler’s staff from between his feet,Until Shiloh [the Messiah, the Peaceful One] comes,And to Him shall be the obedience of the peoples.
