After a moment’s consideration Bathsheba assented, beckoning to Gabriel, who hastened up into the coveted atmosphere.
An unconscious look of assent in Bathsheba’s eyes betrayed that something more than his coldness had made her also feel that Liddy would be superfluous in the suggested scene.
Liddy, without exactly understanding everything, or anything, in this episode, assented, and they walked together further among the trees.
Then out came her trouble before she was aware; and she told him how she had again got into the toils; what Boldwood had asked her, and how he was expecting her assent.
At first Bathsheba assented with a mien of indifference to his proposition that they should go on to the church at once with their burden; but immediately afterwards, following Gabriel to the gate, she swerved to the extreme of solicitousness on Fanny’s account, and desired that the girl might be brought into the house.
There are no more uses of "assent" in the book.
