John Calvin on John 19:29

29. And, having filled a sponge with vinegar, they fixed it on hyssop. When he says that they fixed the sponge on hyssop, the meaning is, that they fastened it to the end of a bunch of hyssop, that it might be raised to Christ’s mouth; for, in that country, hyssops grow as large as small shrubs, “Car l’a les hyssopes sont grans comme petits arbnsseaux.”
