The Greek adverb hosakis means 'as often as' or 'whenever' — expressing repetition tied to a specific event or frequency. It occurs 3 times in the New Testament (1 Corinthians 11:25, 26; Revelation 11:6) and carries the force of 'each and every time this happens.'
The two uses in 1 Corinthians 11 make hosakis theologically weighty. 'This cup is the new covenant in my blood; do this, as often as you drink it, in remembrance of me. For as often as you eat this bread and drink this cup, you proclaim the Lord's death until he comes.' Every celebration of the Lord's Supper is an act of proclamation — the repeated act of communion announces the Gospel of Christ's death. Hosakis ties frequency to theology: the Supper is not a one-time event but an ongoing declaration. Revelation 11:6 uses it for the Two Witnesses' power — 'they have power to turn the waters into blood and to strike the earth with every kind of plague as often as they want.'
