May the praise of God be in their mouths and a double-edged sword in their hands,
Psalm 149:6
Some have laid claim to the idea that this is somehow, primarily, an End Times Psalm. Nothing could be further from the truth.
Failure to recognize the power and authority of the Kingdom leads one to bad exegesis. Remember, Peter was said to have the Keys of the Kingdom, and could bind and lose at will (and, hence, as a body, so do we). These are the already bound things in heaven, so it is the execution of the written judgments spoken of. Again, whether this is a prophecy of what was to come, or then experience of the tabernacle worshippers that was entirely a foreshadowing of the church age is also in question. It seems clear that the singers literally did this in their worship to God at the time, and, because David’s tent was a prophetic picture of the New Covenant, it is what we do every time we lift high praises to God.
