Jehovah
And when Saul enquired of the LORD, the LORD answered him not, neither by dreams, nor by Urim, nor by prophets. 1 Samuel 28:6
The LORD here is Jehovah, the premortal Jesus Christ, who gives revelation through dreams, the Urim, and prophets. Because Saul had rejected His word, the heavens were silent to him.
How we know: Jehovah is the premortal Christ (Abraham 1:16; D&C 110:3–4)
