As I live (ζω εγω). "I live." The LXX here (Isaiah 45:23) has κατ' εμαυτου ομννυω, "I swear by myself."

Shall confess to God (εξομολογησετα τω θεω). Future middle of εξομολογεω, to confess openly (εξ) with the accusative as in Matthew 3:6. With the dative as here the idea is to give praise to, to give gratitude to (Matthew 11:25).
