Charles H. Spurgeon on Psalms 119:138

Thy testimonies that thou hast commanded are righteous and very faithful. All that which God hath testified in his word is right and truthful. It is righteous, and may be relied upon for the present; it is faithful, and may be trusted in for the future. About every portion of the inspired testimonies there is a divine authority, they are issued and published by God's command, and they bear the impress of the royal style which carries omnipotence about it. Not only the precepts but the promises also are commanded of the Lord, and so are all the teachings of Scripture. It is not left to our choice whether we will accept them or no; they are issued by royal command, and are not to be questioned. Their characteristic is that they are like the Lord who has proclaimed them, they are the essence of justice and the soul of truth. God's word is righteous and cannot be impeached; it is faithful and cannot be questioned it is true from the beginning, and it will be true unto the end.

Dwell upon that "sweet word" "very faithful." What a mercy that we have a God to deal with who is scrupulously faithful, true to all the items and details of his promises, punctual to time, steadfast during all time. Well may we risk all upon a word which is" ever faithful, ever sure."
