And Zacharias said unto the angel, Whereby shall I know this? for I am an old man, and my wife well stricken in years.

Because of the tender mercy of our God, Whereby the dayspring from on high shall visit us,

who shall speak unto thee words, whereby thou shalt be saved, thou and all thy house.

For ye received not the spirit of bondage again unto fear; but ye received the spirit of adoption, whereby we cry, Abba, Father.

So then let us follow after things which make for peace, and things whereby we may edify one another.

It is good not to eat flesh, nor to drink wine, nor to do anything whereby thy brother stumbleth.

whereby, when ye read, ye can perceive my understanding in the mystery of Christ;

who shall fashion anew the body of our humiliation, that it may be conformed to the body of his glory, according to the working whereby he is able even to subject all things unto himself.

Wherefore, receiving a kingdom that cannot be shaken, let us have grace, whereby we may offer service well-pleasing to God with reverence and awe:

whereby he hath granted unto us his precious and exceeding great promises; that through these ye may become partakers of the divine nature, having escaped from the corruption that is in that world by lust.

Little children, it is the last hour: and as ye heard that antichrist cometh, even now have there arisen many antichrists; whereby we know that it is the last hour.
