Matthew Poole and continuators on Isaiah 65:16

16 That he who blesseth himself in the Earth, shall bless himself in the God of truth , and he that sweareth in the Earth, shall swear by the God of truth , because the former troubles are forgotten, and because they are hid from mine eyes .

I will bring it to pass, that over all the world, if any man bless himself, or bless another it shall be in God, Amen. So the Heb. (we translate it the God of truth) Amen is a name given to Christ, Rev. 3. 14. [illegible: 1 word] things saith the Amen, the faithful and true witness, being here applied to God, many think it makes a great proof of the God-head of Christ, and judge the sense of this text to be: That under the times of the Gospel men should not bless themselves (as before) in the names of Abraham, & Isaac, and Iacob, but in the name of Christ, in the God Amen, nor is this an improbable sense. Others taking it more appellatively by Elohim, Amen, here understand that God, who shews himself true and faithful in his promises.

In like manner it is prophesied, that those that swear, (by which some understand worship God, others calling God to be a witness) should swear by the God of truth; or in the God of truth. Either worshipping God in Christ the Amen, or calling the faithful God to attest their sincerity, or swearing by that God who hath approved his truth and faithfulness by saving and delivering his people.

because they shall see what God promised is fulfilled, the troubles of his people are at an end, and they are hid from Gods Eyes, that is, they are at an end.
