Genesis 24:20

trough There was a separate receptacle, probably of stone, for watering the animals; Rebekah empties the rest of her pitcher into this trough, and probably has to fill it several times in order to give water enough for the 10 camels 1 [21].

[21] Times, p. 4, Aug. 18, 1913, "Studies in the Zoological Gardens, 4." "However -patient of thirst," in Thomson's phrase, the camel may be … it is also true that it drinks inordinate quantities when it gets the chance.… It is recorded that an individual [camel] has drunk as much as 20 gallons at a sitting, a fact which throws new light on the incident of Rebekah at the well. Abraham's servant … had ten camels, and after he had refreshed himself from Rebekah's pitcher, -she said, I will draw water for thy camels also, until they have done drinking.… And the man, wondering at her, held his peace.…" As well he might. -Until they have done drinking" the words were written by one who knew camels; and Rebekah's acts of kindness to the stranger and his beasts were of larger proportions than the casual reader of these days might infer."
