Terûmāh derives from the verb rûm (H7311), 'to lift up, be high.' The offering was 'heaved' or 'lifted' toward God as an act of presentation and dedication. The word appears 76 times and covers multiple types of sacred contributions: portions of sacrifices given to priests (Leviticus 7:14; Numbers 15:19-21), contributions for the Tabernacle construction (Exodus 25:2-3), and tithes. In Ezekiel's vision of the restored land (Ezekiel 48), the terûmāh refers to a sacred portion of land set aside for priests and Levites.
The terûmāh system embedded a theology of proportion and firstfruits into Israel's economic life. Before any harvest could be used, a 'heave offering' had to be lifted to God — acknowledging that the whole belonged to him and the portion retained was his gift. This prevented the assumption that wealth was self-generated or purely owned. The freewill offering spirit is captured in Exodus 35:5: 'From what you have, take an offering for the LORD. Everyone who is willing is to bring to the LORD an offering.' The New Testament continues this principle: 'Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver' (2 Corinthians 9:7).
