Terûmiyyāh (תְּרוּמִיָּה) means offering, contribution, gift. Related to terûmāh (heave offering). Appears in the context of temple offerings.
Ezekiel 48:12: the consecrated portion will be 'a special gift (terûmiyyāh) to them out of the sacred portion of the land.' In Ezekiel's temple vision, this word describes land set apart for priestly service — a voluntary consecration of the best to God. The principle runs through Scripture: the firstfruits, the tithe, the freewill offering — all express the truth that everything belongs to God and we return a portion in grateful worship. 2 Corinthians 9:7: 'God loves a cheerful giver.'
