He brought me forth also into a large place - He enabled me to clear the country of my foes, who had before cooped me up in holes and corners. This appears to be the allusion.
He brought me forth also into a large place - Instead of being hemmed in by enemies, and straitened in my troubles, so that I seemed to have no room to move, he brought me into a place where I had ample room, and where I could act freely. Compare the note at Psalm 4:1.
He delivered me - He rescued me from my enemies and my troubles.
Because he delighted in me - He saw that my cause was just, and he had favor toward me.
