Комментарий к Берешит 24:11

ויברך הגמלים means HE MADE THEM KNEEL (Genesis Rabbah 59:11).

ויברך הגמלים, a camel has two knees one above the other; therefore it needs two motions to go down on its knees and because of its height it cannot drink before having thus lowered itself to the level of the trough. This is what the sages referred to in Chulin 76 when they said וכנגדו בגמל ניכר, that a spot known as the ארכובה in cattle is clearly recognisable on the foreleg of a camel.

ויברך הגמלים, he made them go down on their knees in order that the jugs of water could be presented to them for them to drink. While all this was happening he prayed to G’d to arrange for the right kind of girl to put in an appearance.
