Psalms 5:11,12

‘But let all those who put their trust in you rejoice,

Let them shout for joy because you defend them,

Let those also who love your name be joyful in you,

For you will bless the righteous,

O Yahweh you will compass him with favour as a great shield.'

But in contrast let those whose trust is in YHWH and His covenant, those who love His name, rejoice, aware that He is defending them; let them shout for joy because they know that He will bless the righteous. So His defence of them and His blessing are causes of their great rejoicing. They know that the huge shield of His favour protects and watches over them.

‘Your name.' That is His being, attributes and character. They love Him for what He is, the Deliverer of His people. See Psalms 69:36; Psalms 119:132.

So the psalm began with confidence and ends with triumph, triumph in the God of the righteous. Triumph in the name of the One Whose being, attributes and character they know so well, the One in Whom they can put their trust without any fear of being confounded.
