2 Samuel 7:18

Then went King David in Into the tabernacle. And sat before the Lord That is, before the ark, the symbol of the divine presence, and where God was then peculiarly present, and was believed by David to be so. David probably sat for a season, while he meditated on these things, and then altered his posture and betook himself to prayer. It must be observed, however, that the Hebrew word, ישׁב, jashab, here rendered sat, may with equal propriety be translated, remained before the Lord. The Hebrews never addressed prayers or praises to God but either standing up or prostrate on the earth, and even their kings are always described as standing when they prayed or gave thanks in the temple. See Ezekiel 46:1; compared with 2 Kings 11:14, and 2 Chronicles 23:13. Nor is there any other posture of worship mentioned in Scripture, but standing, or kneeling, or falling on the face. Who am I, O Lord God? How infinitely unworthy am I and my family of this great honour and happiness! Thus David begins his address to God in a becoming spirit of humility and self-abasement, acknowledging his utter unworthiness of the blessings which God had already bestowed on him.
