Bible Verse–Ecclesiastes 7:9

But I certify you, brothers, that the gospel which was preached of me is not after man. For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ.

But above all things, my brothers, swear not, neither by heaven, neither by the earth, neither by any other oath: but let your yes be yes; and your no, no; lest you fall into condemnation.

Now no chastening for the present seems to be joyous, but grievous: nevertheless afterward it yields the peaceable fruit of righteousness to them which are exercised thereby.
