John Gill Commentary Psalms 119:167

"My soul hath observed thy testimonies; And I love them exceedingly." — Psalms 119:167 (ASV)

My soul has kept your testimonies
The word of God, which he kept cordially and heartily; and in his heart, laid it up there; and with his whole soul observed the doctrines and kept the precepts of it;

and I love them exceedingly;
and kept them from a principle of love, and not with mercenary and selfish views; and this love was exceeding great, not cold nor lukewarm, but ardent and fervent, love in the superlative degree.
