'Sware' in the Bible

So I sware in my wrath, They shall not enter into my rest.)

And to whom sware he that they should not enter into his rest, but to them that believed not?

for we do enter into the rest -- we who did believe, as He said, 'So I sware in My anger, If they shall enter into My rest -- ;' and yet the works were done from the foundation of the world,

For when God made promise to Abraham, because he could swear by no greater, he sware by himself,

(For those priests were made without an oath; but this with an oath by him that said unto him, The Lord sware and will not repent, Thou art a priest for ever after the order of Melchisedec:)
