The Greek adverb ektenesteron is the comparative form of ektenōs, meaning "stretched out" or "extended." As a comparative adverb, it means "more earnestly," "more intensely," or "more fervently." It appears in Luke 22:44 describing Jesus' prayer in Gethsemane: "And being in agony, he prayed more earnestly."
Ektenesteron (more earnestly) describes the intensity of Jesus' prayer in His darkest moment — Gethsemane. The word comes from a root meaning "stretched out," as if in desperate reaching. In Luke 22:44, Jesus prays ektenesteron as His sweat fell like drops of blood. This is the model of prayer in extremity: not a casual request but a soul poured out before God. Peter uses the cognate ektenōs to describe the church's fervent prayer for him when imprisoned (Acts 12:5). Earnest prayer is stretched prayer — extended beyond what feels natural.
