There are lines in Psalm 109 that are about someone that David loved, but became his adversary.

Those same lines are also prophetic about Judas, whom Jesus called, "Friend", who betrayed Jesus:

Psalms 109:4 For my love they are my adversaries: but I give myself unto prayer.

  5 And they have rewarded me evil for good, and hatred for my love.

  6 Set thou a wicked man over him: and let Satan stand at his right hand.

  7 When he shall be judged, let him be condemned: and let his prayer become sin.

  8 Let his days be few; and let another take his office.

The connection to Judas was given by the Holy Ghost, through Peter, when he spoke the following:

Acts 1:16 Men and brethren, this scripture must needs have been fulfilled, which the Holy Ghost by the mouth of David spake before concerning Judas, which was guide to them that took Jesus.

  20 For it is written in the book of Psalms, Let his habitation be desolate, and let no man dwell therein: and his bishoprick let another take.

Also, in his prayer to the Father, Jesus referred to Judas as the son of perdition.

John 17:12 While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled.

And that title of son of perdition is also shown to be prophetically speaking about the antichrist:

II Thessalonians 2:3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;

So, since Psalm 109 was speaking of one that went against David, but was prophetically speaking about the son of perdition who betrayed Jesus;

Could Psalm 109, then, be also prophetically speaking about the future son of perdition, who will go against Jesus?

If so, then his title as antichrist, might also be pictured by this line in Psalm 109:

Psalms 109:6 Set thou a wicked man over him: and let Satan stand at his right hand.

Which is in contrast to Jesus:

Acts 7:55 But he, being full of the Holy Ghost, looked up stedfastly into heaven, and saw the glory of God, and Jesus standing on the right hand of God,

So, if line 6 may also prophetically be speaking about the antichrist:

Psalms 109:6 Set thou a wicked man over him: and let Satan stand at his right hand.

Does that therefore mean that, spiritually, the antichrist is on the left hand of the devil?
