Deuteronomy 11:10

With thy foot — That is, with great pains and labour of thy feet, partly by going up and down to fetch water and disperse it, and partly by digging furrows with thy foot, and using engines for distributing the water, which engines they thrust with their feet. For tho' the river Nile did once in a year overflow the grounds, and made them fruitful, yet often it failed them, at least in part, and then they were put to great pains about their ground. And when it did overflow sufficiently, and left its mud upon the earth, yet that mud was in a little time hardened, and needed another watering, and much digging and labour both of the hand and feet, especially in places more remote from that river; which inconvenience Canaan was free from.
