Baruch 3:35-37

30 Who has gone over the sea, and found her, and will buy her for pure gold? 31 No one knows the way to her, or is concerned about the path to her. 32 But the one who knows all things knows her, he found her by his understanding. The one who prepared the earth for all time filled it with four-footed creatures; 33 the one who sends forth the light, and it goes; he called it, and it obeyed him, trembling; 34 the stars shone in their watches, and were glad; he called them, and they said, "Here we are!" They shone with gladness for him who made them. 35 This is our God; no other can be compared to him. 36 He found the whole way to knowledge, and gave her to his servant Jacob and to Israel, whom he loved. 37 Afterward she appeared on earth and lived with humankind.

Hilary of Poitiers On the Trinity 4.42

As you have listened already to Moses and Isaiah, so listen now to Jeremiah inculcating the same truth as they: This is our God, and there shall be none other likened unto Him, Who has found out all the way of knowledge, and has given it unto Jacob His servant and to Israel His beloved. Afterward did He show Himself upon earth and dwelt among men. For previously he had said, And He is Man, and Who shall know Him ? Thus you have God seen on earth and dwelling among men. Now I ask you what sense you would assign to No one has seen God at any time, save the Only-begotten Son, which is in the bosom of the Father, when Jeremiah proclaims God seen on earth and dwelling among men? The Father confessedly cannot be seen except by the Son; Who then is This who was seen and dwelt among men? He must be our God, for He is God visible in human form, Whom men can handle.
