Colossians 2:13 And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses; 2:14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross; 2:15 And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it. 2:16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days: 2:17 Which are a shadow of things to come; but the body is of Christ.
Colossians 2:20 Wherefore if ye be dead with Christ from the rudiments of the world, why, as though living in the world, are ye subject to ordinances, 2:21 (Touch not; taste not; handle not; 2:22 Which all are to perish with the using; ) after the commandments and doctrines of men? 2:23 Which things have indeed a shew of wisdom in will worship, and humility, and neglecting of the body; not in any honour to the satisfying of the flesh.
He is referring to The Law - which is a system of Commandments CONTAINED IN ordinances.

Galatians 4:9 But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly elements, whereunto ye desire again to be in bondage? 4:10 Ye observe days, and months, and times, and years. 4:11 I am afraid of you, lest I have bestowed upon you labour in vain.

Ephesians 2:1 And you hath he quickened, who were dead in trespasses and sins; 2:2 Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience: 2:3 Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 2:9 Not of works, lest any man should boast. 2:10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them. 2:11 Wherefore remember, that ye being in time past Gentiles in the flesh, who are called Uncircumcision by that which is called the Circumcision in the flesh made by hands; 2:12 That at that time ye were without Christ, being aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world: 2:13 But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ. 2:14 For he is our peace, who hath made both one, and hath broken down the middle wall of partition between us; 2:15 Having abolished in his flesh the enmity, even the law of commandments contained in ordinances; for to make in himself of twain one new man, so making peace; 2:16 And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby: 2:17 And came and preached peace to you which were afar off, and to them that were nigh. 2:18 For through him we both have access by one Spirit unto the Father. 2:19 Now therefore ye are no more strangers and foreigners, but fellowcitizens with the saints, and of the household of God;
