'First' in the Bible

When Jehovah spake at the first by Hosea, Jehovah said unto Hosea, Go, take unto thee a wife of whoredom and children of whoredom; for the land doth commit great whoredom, departing from Jehovah.

And she shall follow after her lovers, but she shall not overtake them; and she shall seek them, but shall not find them: then shall she say, I will go and return to my first husband; for then was it better with me than now.

I found Israel like grapes in the wilderness; I saw your fathers as the first-ripe in the fig-tree at its first season: but they came to Baal-peor, and consecrated themselves unto the shameful thing, and became abominable like that which they loved.
