Charles Ellicott Commentary Genesis 29:11

"And Jacob kissed Rachel, and lifted up his voice, and wept." — Genesis 29:11 (ASV)

Jacob kissed Rachel ... and wept. —Jacob first made himself useful to Rachel, and then discloses to her who he is, claims her as a cousin, and kisses her. Then, overcome with joy at this happy termination of his long journey, and at finding himself among relatives, he can restrain his feelings no longer, but bursts into tears. In this outburst of emotion we see the commencement of his lifelong affection for the beautiful child whom he thus opportunely met.
