Most modern Bibles have footnotes to indicate passages that have disputed source documents. Bible Commentaries also discuss these, sometimes in great detail. While many variations have been discovered between early copies of biblical texts, almost all have no importance, as they are variations in spelling, punctuation, or grammar. Also, many of these variants are so particular to the Greek language that they would not appear in translations into other languages. For example, order of words (i.e. "man bites dog" versus "dog bites man") often does not matter in Greek, so textual variants that flip the order of words often have no consequences.
