Jacob kissed Rachel - A simple and pure method by which the primitive inhabitants of the earth testified their friendship to each other, first abused by hypocrites, who pretended affection while their vile hearts meditated terror, (see the case of Joab), and afterwards disgraced by refiners on morals, who, while they pretended to stumble at those innocent expressions of affection and friendship, were capable of committing the grossest acts of impurity.
And lifted up his voice - It may be, in thanksgiving to God for the favor he had shown him, in conducting him thus far in peace and safety.
And wept - From a sense of the goodness of his heavenly Father, and his own unworthiness of the success with which he had been favored. The same expressions of kindness and pure affection are repeated on the part of Laban, Genesis 29:13.

And Jacob kissed Rachel,.... Which he did in a way of courtesy and civility; this was done after he had acquainted her with his relation to her; he saluted her upon that:
and lifted up his voice, and wept; for joy at the providence of God that had brought him so opportunely to the place, and at the sight of a person so nearly related to him; and who he hoped would be his wife, and was the person designed of God for him.
