Asiph (אָסִיף) refers to the harvest ingathering, specifically the autumn harvest of fruits, grain, and produce. It is the noun form of asaph (אָסַף, to gather). The word appears in Exodus 23:16 and 34:22 identifying the "Feast of Ingathering" (chag ha-asiph), which is the Festival of Booths (Sukkot) celebrating the completion of the harvest.
The asiph — the ingathering festival — is rich in eschatological meaning. The harvest metaphor pervades both Testaments as an image of God's ultimate gathering of His people. Jesus used it explicitly: "The harvest is plentiful but the workers are few" (Matthew 9:37). Revelation's harvest imagery (14:14–16) portrays the final gathering of souls. Sukkot's joy — dwelling in temporary booths, celebrating God's provision — points to the eternal feast when God will "tabernacle" among His people (Revelation 21:3).
