Charles Ellicott Commentary Hosea 6:2-3

"After two days will he revive us: on the third day he will raise us up, and we shall live before him. And let us know, let us follow on to know Jehovah: his going forth is sure as the morning; and he will come unto us as the rain, as the latter rain that watereth the earth." — Hosea 6:2-3 (ASV)

Render, So that we shall live in his presence, and shall know and strive after the knowledge of Jehovah, whose coming forth is sure, like the dawn (another play on Hosea 6:15, I will return to my place, etc.), so that he may come as the plentiful (dashing) rain for us, as the latter rain (needed for the ripening corn) which waters the earth.
