There is no "definite article" ('the') used in the verse
The text states this:
"And I said to him, "My lord, you know." And he said to me, "
These are the ones coming out of the great tribulation, and they have washed their robes and made them white in the blood of the Lamb."

<--take note of the definite article used in the Greek in this verse:
"3588
tēs " ...translated in English as
'the'... "THE tribulation THE great"... so yes, "the "definite article ['
THE']"
IS present in the verse]
nor did all of those seen there lived and/or died during the Great Tribulation.
The text itself states, "These are the
ones coming out of THE GREAT TRIBULATION"...
... so I'll go with the text itself, what the text itself
clearly states, rather than to go with your
injected idea of what the text states.
That group is all who have been through any tribulations throughout the church age.
Disagree, based on what the text itself clearly states: "These are the
ones coming out of
THE GREAT TRIBULATION"...
... which is a VERY SPECIFIC,
future,
LIMITED (3.5 yr) time-period... specifically,
the second half of the "7 yr period" in its entirety.
And
vv.16-17 (
speaking of those same persons)
corresponds with Isaiah 49:10 (an
earthly Millennial Kingdom passage), referring to their "destination-location"
Many there did go through the Great Tribulation of the end times but most did not as they lived and died in different periods of time.
This particular passage (vv.9,14-17) speaks
ONLY of
"the ones coming out of THE GREAT TRIBULATION" per the text (i.e. the second half of the FUTURE "7 yr period" leading UP TO Christ's Second Coming
to the earth / RETURN
to the earth Rev19)...
The passage in Rev7:9,14-17 is NOT referencing all OTHER believers of all OTHER time periods. No.
