Notice what Solomon did before and after he asked for wisdom.
The king went to an important place of worship and sacrificed 1,000 burnt offerings to the Lord. That night the Lord appeared to Solomon in a dream (from 1 Kings 3:4-5).”
“Solomon woke up, returned to Jerusalem, stood before the Ark of the Lord’s Covenant, and sacrificed burnt offerings and peace offerings (from 1 Kings 3:15).”
