YOUR WORD IS A LAMP TO MY FEET AND A LIGHT TO MY PATH
In ancient times, following sunset, the sole source of illumination came from a torch. This torch consisted of a clay base about the size of a palm, filled with oil, which would burn through the wick.
In this Psalm, the word of God is likened to a torch (or a lamp, as we might say in English). Just as light is indispensable for a nighttime journey, keeping us safe from harm, so too is the word of God an essential beacon in this dark and sinful world, illuminating our path toward salvation.
