IMPORTANT: All Scripture text has context and background. Scripture should never be read literally or in isolation. Always seek clarification from religious scholars and teachers. In general, Scripture adheres to four principles: (1) Literal Meaning - What the Scripture says (2) Historical Setting - The story events; how the Scripture was understood in its time (3) Grammar - The surrounding sentence and paragraph; textual context (4) Synthesis - A comparison with similar Scripture to give a better contextual understanding
