Rut 4:9

4:9 Then Boaz said to the leaders and all the people, “You are witnesses today that I have acquired from Naomi all that belonged to Elimelech, Kilion, and Mahlon.

Yesaya 8:2

8:2 Then I will summon ¹  as my reliable witnesses Uriah the priest and Zechariah son of Jeberekiah.”

[8:2]  ¹ tn The form in the text is a cohortative with prefixed vav (ו), suggesting that the Lord is announcing what he will do. Some prefer to change the verb to an imperative, “and summon as witnesses,” a reading that finds support from the Qumran scroll 1QIsa^a. Another option is to point the prefixed conjunction as a vav consecutive and translate, “So I summoned as witnesses.” In this case Isaiah is recalling his response to the Lord’s commission. In any case, the reference to witnesses suggests that the name and the child who bears it will function as signs.
