A Final Cry is Now Made Directly To YHWH (Psalms 21:13).
‘Be exalted, O YHWH, in your strength,
So will we sing and praise your power.'
And their final plea is that YHWH might be exalted, revealing His strength. Thus will they be able to sing and praise His power. In the end it is the glory of God that matters, not the success of men, and it is that which should be our main concern, and it should always lead us to praise and worship.
