[the Bull ] indicates to the Egyptians the time for ploughing the earth, which is done with oxen.
Mount Taurus, in Asia. In Judges xv. 3-19 we have an account of Samson and the jawbone, but probably Chamor (translated an ass) was the name of a hill or series of hills like Taurus, and should not have been translated. Similarly, Lehi (translated a jawbone) is probably a proper name also, and refers to a part of Chamor. If so, the meaning is, When he (Samson) came to Lehi, the summit of Mount Chamor, seeing a moist boulder, he broke it off and rolled it on his foes. Down it bounded, crushing “heaps upon heaps” of the Philistines. Where the boulder was broken off a spring of water jetted out, and with this water Samson quenched his thirst.
What is now called the Mountain of St. Patrick was previously called “Mount Eagle” - in Irish, Cruachan Aichle.
