In the secret of - in the innermost shrine, the surest asylum, shall He hide me (1 Kings 2:28). So He hid Moses in the secret of His tabernacle, when the people would have stoned him (Numbers 14:10). The term "tabernacle" proves that the psalm was written before the time of Solomon, when the temple was built. Compare Psalms 31:20.
