Charles H. Spurgeon on Psalms 25:10

All the paths of the Lord, (twxra) orchoth signifies the tracks or ruts made by the wheels of wagons by often passing over the same ground. Mercy and truth are the paths in which God constantly walks in reference to the children of men; and so frequently does he show them mercy, and so frequently does he fulfil his truth, that his paths are easily discerned. How frequent, how deeply indented, and how multiplied are those tracks to every family and individual! Wherever we go, we see that God's mercy and truth have been there by the deep tracks they have left behind them. But he is more abundantly merciful to those who keep his covenant and his testimonies; i.e., those who are conformed, not only to the letter, but to the spirit of his pure religion. Adam Clarke.
