Elijah comes from Hebrew and is traditionally translated as "my God is Yahweh," a name carried by a prophet known for uncompromising conviction. It's commonly read as suggesting devotion held firmly rather than loosely -- a name associated with steadiness of belief more than outward display.
The fortunate stars confer great felicity, when they shall be received of each other in their proper houses; and when the evil planets are so received, they refrain from doing much mischief. - William Lilly (1602.-1681.)
