20 And now, because you did not believe my words, which will be fulfilled in their time, you will be silent, unable to speak, until the day these things take place.”

Darby

20 and behold, thou shalt be silent and not able to speak, till the day in which^D7164 these things shall take place, because thou hast not believed my words, the which shall be fulfilled in their time.

Darby Bible Notes

which - 'Which are such as shall be.' giving the character, not merely a relative pronoun. I have imitated an expression of the Authorized Version, by adding the article, which though somewhat antiquated, gives in a measure the idea of character, and may serve to distinguish the sense; so ch. 10.42.

KJV

20 And, behold, thou shalt be dumb, and not able to speak, until the day that these things shall be performed, because thou believest not my words, which shall be fulfilled in their season.

Strong's

20 And ^G2532, behold^G2400, thou^G2071 shalt be dumb^G4623, and^G2532 not^G3361 able^G1410 to speak^G2980, until^G891 the day^G2250 that^G3739 these things^G5023 shall be performed^G1096, because^{G473 G3739} thou believest^G4100 not^G3756 my^G3450 words^G3056, which^G3748 shall be fulfilled^G4137 in^G1519 their^G846 season^G2540.
