'Truly' in the Bible

The woman answered, “I do not have a husband.” Jesus said to her, “You have correctly said, ‘I do not have a husband’;

for you have had five husbands, and the man you are now living with is not your husband. You have said this truthfully.”

and they told the woman, “We no longer believe just because of what you said; for [now] we have heard Him for ourselves and know [with confident assurance] that this One is truly the Savior of [all] the world.”

Look, He is speaking publicly, and they say nothing to Him! Is it possible that the rulers really know that this is the Christ?

So Jesus was saying to the Jews who had believed Him, “If you abide in My word [continually obeying My teachings and living in accordance with them, then] you are truly My disciples.

They answered, “Abraham is our father.” Jesus said to them, “If you are [truly] Abraham’s children, then do the works of Abraham and follow his example.

even as the Father knows Me and I know the Father—and I lay down My [very own] life [sacrificing it] for the benefit of the sheep.

Now [at last] they know [with confident assurance] that all You have given Me is from You [it is really and truly Yours].
