Albert Barnes Commentary Psalms 119:134

"Redeem me from the oppression of man: So will I observe thy precepts." — Psalms 119:134 (ASV)

Deliver me from the oppression of man – From constraint from man, so that I may be free to act as I please. Give me true religious liberty, and let me not be under any compulsion or constraint. The word translated “deliver” is the one that is usually translated “redeem.” It is used here in the broad sense of deliverance; and the prayer is an expression of what the true friends of religion have always sought, desired, and demanded – “freedom” of opinion – the richest blessing that humanity can enjoy.

So will I keep your precepts – My heart inclines to that; I desire it; and if permitted to act without constraint, I will do it. As it is the purpose and the wish of my soul, I pray that all hindrances to the free exercise of my religion may be removed. How often has this prayer been offered in times of persecution! By how many millions of people on earth might it even now be offered! What a blessing it is to those who are free from oppressive laws, that they are permitted to carry out the wishes of their hearts and to worship God according to the dictates of their conscience, with no one to trouble them or make them afraid.
