What Does Exodus 23:16 Mean?

The Feast of Harvest (Weeks/Pentecost) is the covenant calendar's Firstfruits festival: the first Wheat harvest celebration that occurs seven weeks after the Barley firstfruits (Leviticus 23:15-16). The "firstfruits of your labor, of what you sow in the field" brought to YHWH is the acknowledgment-offering at the agricultural year's midpoint: the spring planting has produced its first harvest, and the first evidence of that harvest belongs to YHWH before any of it belongs to the household. The Firstfruits feast is the covenant community's annual acknowledgment that agricultural productivity is YHWH's before it is theirs.

The Feast of Ingathering (Tabernacles/Booths) "at the end of the year, when you gather in from the field the fruit of your labor" is the harvest's completion celebration: the entire agricultural year's produce gathered in, the community sustained for another year, YHWH's provision documented in the full storehouses. The Feast of Ingathering is also called the Feast of Booths (Leviticus 23:42-43) because Israel lived in temporary shelters during it, commemorating the wilderness wandering and the dependence on YHWH's daily provision rather than permanent structures. Harvest abundance and wilderness vulnerability are simultaneously commemorated.

Acts 2:1 places the Spirit's Pentecost arrival at the Feast of Harvest/Weeks: "when the day of Pentecost arrived, they were all together in one place." The feast that existed to bring the firstfruits of the wheat harvest before YHWH becomes the occasion when YHWH brings the firstfruits of the new covenant harvest, those who believe through the Spirit, before himself. James 1:18 describes believers as "a kind of firstfruits of his creatures." The agricultural firstfruits festival becomes the eschatological firstfruits event: the Spirit's harvest of the new covenant community is the "firstfruits" of the world's ultimate harvest under God.
