A.T. Robertson Commentary Mark 2:22

"And no man putteth new wine into old wineskins; else the wine will burst the skins, and the wine perisheth, and the skins: but [they put] new wine into fresh wine-skins." — Mark 2:22 (ASV)

But new wine into fresh wineskins (αλλα οινον νεον εις ασκους καινους). Westcott and Hort bracket this clause as a Western non-interpolation though omitted only in D and some old Latin MSS. It is genuine in Lu 5:38 and may be so here.
