Isaiah 8.17
Septuagint

kai erei, menw ton qeon ton apostreyanta to proswpon autou apo tou oikou Iakwb, kai pepoiqwV esomai ep autw

New Testament - Hebrews 2.13

kai palin: egw
esomai pepoiqwV ep autw

Septuagint

And one shall say, I will wait for God, who has turned away his face from the house of Jacob, and I will trust in him

New Testament

And again, I will put my trust in him

Masoretic Text

I will wait for Jehovah, that hideth his face from the house of Jacob, and I will look for him

Comments:  The NT and the LXX agree.  The MT replaces “trust in” with “look for.”  The RSV translates the final phrase as “I will hope in him.”
