ISA 45:23

23 I swore in myself, a word of rightfulness shall go out of my mouth, and it shall not turn again; for each knee shall be bowed to me, and each tongue shall swear. (I swore to myself, a word of righteousness went out of my mouth, and it shall not return again void, or empty; yea, every knee shall bow to me, and every tongue shall swear, or vow, to be loyal to me.)
