The use of the plural number is here remarkable. It may imply a reference to facts to which Jesus and His followers bore testimony, as well known to them : but it may have a deeper reference to the three who give testimony in heaven and on earth. " Since the Father and the Holy Ghost were in Him," observes St. Cyril of Alexandria, " He used the plural number, speaking of those who bore witness, so that in a manner, according to the law, every thing was established by two or three witnesses."
