2Ch 8:11 And Solomon brought up the daughter of Pharaoh out of the city of David unto the house that he had built for her: for he said, My wife shall not dwell in the house of David king of Israel, because the places are holy, whereunto the ark of the LORD hath come.
Here we have the importance of marrying the person God has chosen for you. Solomon, the son of David, has married the daughter of Pharaoh. Pharaoh (devil) was King of Egypt which is a type of the world. Due to her lineage Solomon knew she could not live in his father’s house so he built her a separate home. One should never consider marrying someone that must be brought into your heavenly Father’s home. They must already be a part of your Father’s House (2Cor 6:14). If you want to ensure in-law issues then marry one whose spiritual father is Pharaoh, King of Egypt.
