Weak And Beggarly Elements

Gal 4:8 Howbeit then, when ye knew not God, ye did service unto them which by nature are no gods.
Gal 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?
Gal 4:10 Ye observe days, and months, and times, and years.
Gal 4:11 I am afraid of you, lest I have bestowed upon you labour in vain.
Gal 4:12 Brethren, I beseech you, be as I am; for I am as ye are: ye have not injured me at all.
Gal 4:13 Ye know how through infirmity of the flesh I preached the gospel unto you at the first.
Gal 4:14 And my temptation which was in my flesh ye despised not, nor rejected; but received me as an angel of God, even as Christ Jesus.
