Matthew Poole and continuators on Luke 3:23

23 And Jesus himself began to be about thirty years of age, being (as was supposed) the son of Joseph, which was the son of Heli,

Here is amongst Criticks a little dispute, whether our blessed Lord at his Baptisme (after which he soon began his Publick Ministry) was full thirty years of Age [non-Latin text not transcribed] and [non-Latin text not transcribed] in the Greek, give occasion to the doubt. Those who judge that he was thirty compleat, conceive that the Age before which the Priests and Levites, did no Service in the Tabernacle of God, Num. 4.3. commanded the number of them to be taken from thirty years old to fifty, and it was done accordingly, v. 34, 35. &c. David in the latter end of his Life so numbred them, 1 Chron. 23.3. when their number (of that Age) was thirty eight thousand, yet in that Chapter, v. 24. and 27. we find them numbred from twenty years Old and upward (but possibly, that was for some more inferiour Service, in Conformity to this, most think that both Iohn the Baptist, and Christ entred not upon their Publick Ministry, till they were of that Age, but whether they were thirty years of Age, Compleat, or Current, is a question, but so little a one, as deserves no great Study to resolve, the two qualifying Words [non-Latin text not transcribed] and [non-Latin text not transcribed], would incline one to think Christ was but thirty years of Age Current, which is advantaged, by what others tell us, that the Iews ordinarily called a Child two, or three years Old, as soon as it did but enter upon its second or third year. Some think our Saviour was Ten Months above twenty nine years of Age, when he was Baptized, after which he was tempted of the Devil forty Days, before he entred the Publick Ministry, but these are little things. [Being (as was supposed) the Son of Ioseph.] Ioseph was not his Natural Father, tho so supposed by the Jews, Ioseph being indeed his Legal Father, being Married to the Virgin, when our Saviour was Born, Matth. 1.20.
