'Tonight' in the Bible

Go back, my daughters, and go on your way; I am so old now that I may not have another husband. If I said, I have hopes, if I had a husband tonight, and might have sons,

And now, is there not Boaz, our relation, with whose young women you were? See, tonight he is separating the grain from the waste in his grain-floor.

Take your rest here tonight; and in the morning, if he will do for you what it is right for a relation to do, very well, let him do so: but if he will not, then by the living Lord I myself will do so.
