It is ready to burst like new bottles— Bottles of new wine. The epithet new belongs more properly to the wine, as it is in the LXX; in our Saviour's parabolical expression of, putting new wine into old bottles; and as it is more consistent with the nature of things; for, the bottles being made of leather, an old bottle was more liable to be burst by the fermentation of new wine, than a new one.
