Therefore i do not fear the myriad of people, who have set themselves against me all around.

MIDRASH TEHILLIM

1.....(3.7)
...set themselves...
To make war against me. Therefore Moshe, after saying to the people of Israel, If you will say in your hart, These nations are more than I, how will I be able to drive them out? (Devarim - Deuteronomy 7:17), declared: You will not be afraid of them, for the LORD your God is in the midst of you (Devarim - Deuteronomy 7:18,21).

RASHI

1.
...set themselves...
Heb. שתו, an expression of desolation, to destroy. Others say that שתו is like שמו, they placed, like (Exodus 10:1): “in order that I set up (שתי) my signs.”

RADAK

1.
i do not fear the myriad of people
All Israel were with Absalom, except those who were with David in Jerusalem, and had gone out with him, and those who had joined him afterwards.
2.
who have set themselves against me all around.
The interpretation of שתו may be "they have fought." And so "they have taken their stand" (fought, שת שתו ) "at the gate" (Yeshayahu - Isaiah 22:7);
and " He will assail (ישית) thy waves with violence" (Iyov - Job 38:11).
