In Barnabas 4:14 a terse saying, “many are called but few chosen,” is introduced by a phrase that points to use of a written document: “it is written.” This may well be a reference to Matthew 22:14 in its written form, but since there is a similar proverbial saying in 4 Ezra 8:3, the question cannot be readily answered.
