Leviticus 24:1,2 (KJV)
1 And the Lord spake unto Moses, saying,
2 Command the children of Israel, that they bring unto thee pure oil olive beaten for the light, to cause the lamps to burn continually.
Leviticus 24
Never Let Your Light Go Dim
Willful sin tears us away from God and causes our light to go dim and then out completely. Only God can help this to not happen.
