Charles Ellicott Commentary 2 Chronicles 1:7

"In that night did God appear unto Solomon, and said unto him, Ask what I shall give thee." — 2 Chronicles 1:7 (ASV)

In that night did God appear unto Solomon. —1 Kings, In Gibeon did Jehovah appear unto Solomon in a dream of the night. Our text fixes the night as that which followed the sacrifices; the parallel passage explicitly states that it was in a dream that God appeared.

Ask what I shall give thee. —Rather, Ask thou! what shall I give thee?Song of Solomon 1 Kings.
