Ps. 83.3 (against your people)

Against your people / they make plans
and they conspire together / against your treasured one. 

You to your. In the immediately preceding verse, where the enemies first ‘raised their head(s)’, their ‘roaring’ and movement was instigated by their hatred for God: “your enemies”; “those who hate you have raised their heads”. Here, that ‘you’ turns into ‘yours’. While their hatred for God may have been what awoke them, the object of their attack is “your people” and “your treasured ones”. Their hatred for God becomes incarnate in their attempt to destroy his people. In this we see something important: that the (covenantal) bond between God and Israel is the, in a sense, not just the umbilical cord for Israel but also that which represents the ‘throne of God’. For the enemies, if they can destroy Israel, they sever God’s power. Israel is the ‘heart’ of God, that which he most cherishes. She is his ‘treasured ones’. 

Rhetoric. All of this said, we must now consider how this verse operates. It is easy to forget that these psalms were not written to us as readers, but for us to be spoken to God. As such, these words’ intended audience is God. The question then is, why would the psalmist speak these words in particular to God? The answer I believe is that they are part of the petition that opened the psalm. The psalmist is attempting to get God to “speak, not be silent or still” by bringing to his attention, 1) the ‘rising’ of the enemy (vs. 2) and 2) the fact that the object of the enemies’ hatred are God’s treasured ones. It is an appeal to God’s heart and devotion.
