“And the king went to Gibeon to sacrifice there; for that was the great high place: a thousand burnt offerings did Solomon offer upon that altar. In Gibeon the LORD appeared to Solomon in a dream by night: and God said, Ask what I shall give thee.” - 1 Kings 3:4-5.
In spite of the fact that Gibeon belonged to a gentile nation, the Gibeonites, it pleased God to make it a hallowed place for His people to do service to Him. Even in the time of Joshua, Gibeon was made one of the cities to serve as city of refuge. (Joshua 21:17) It was at Gibeon that Solomon went to make sacrifices to God and there God spoke to him in a dream by night. It was here the tabernacle was placed. (2 Chronicles 1:3) Whether a Jew or not, anyone who serves God with good heart condition will find favour with Him. - Acts 10:34, 35; John 9:31.
Moreover St. Paul, asserting that God “will render to every man according to his deeds” went on to say that “To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life: But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath, Tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile; But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile: For there is no respect of persons with God.” - Romans 2:6-11.
