By myself I swear, righteousness shall surely proceed out of my mouth; my words shall not be frustrated; that to me every knee shall bend, and every tongue shall swear by God

For it is written, As I live, saith the Lord, to me every knee shall bow, And every tongue shall confess to God 
 

By myself have I sworn, the word is gone forth from my mouth in righteousness, and shall not return, that unto me every knee shall bow, every tongue shall swear

The MT differs, having “swear” in place of  “confess.”
