Methodius of Olympus

The vine, and that not in a few places, refers to the Lord himself, and the fig tree to the Holy Spirit, as the Lord makes glad the hearts of people and heals them. And therefore Hezekiah is commanded first to make a plaster with a lump of figs—that is, the fruit of the Spirit—that he may be healed—that is, according to the apostle—by love; for he says, “The fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, meekness, temperance;” which, on account of their great pleasantness the prophet calls figs. Micah also says, “They shall sit everyone under his vine and under his fig tree; and none shall make them afraid.” Now it is certain that those who have taken refuge and rested under the Spirit and under the shadow of the Word shall not be alarmed or frightened by him who troubles the hearts of humankind.
