"Green pastures" is Psalm 23:2’s image of YHWH as Shepherd making the saint lie down in tender, well-watered pasture: "He maketh me to lie down in green pastures: he leadeth me beside the still waters." The Hebrew is more specific than the English: neʾot deshe — "pastures of tender grass." This is not just grazing-ground but rest-ground. A sheep lies down only when full and at peace; if hungry, thirsty, frightened, or harassed, it cannot lie down. The Shepherd’s provision is total enough that lying down becomes possible. Modern Christians who cannot rest — sleeping poorly, anxious always — should ask whether they have stopped following the Shepherd, or have wandered beyond the pastures He prepared.
