'Even' in the Bible

Return home, my daughters. Go on, for I am too old to have another husband. Even if I thought there was still hope for me to have a husband tonight and to bear sons,

Where you die, I will die,and there I will be buried.May Yahweh punish me,and do so severely,if anything but death separates you and me.

And she said, I pray you, let me glean and gather after the reapers among the sheaves: so she came, and hath continued even from the morning until now, that she tarried a little in the house.

Boaz then addressed Ruth: "Listen, my daughter! Don't glean in any other field. Don't even leave this one, and be sure to stay close to my women servants.

Ruth knelt before him with her forehead to the ground and said to him, "Why are you so kind and so attentive to me, even though I am a foreigner?"

She responded, "May I continue to find favor in your sight, sir, since you've been comforting me and you have spoken graciously to your servant, even though I am not one of your servants."

And when she was risen up to glean, Boaz commanded his young men, saying, Let her glean even among the sheaves, and reproach her not:

So she gleaned in the field until even, and beat out that she had gleaned: and it was about an ephah of barley.

Ruth the Moabite replied, "He even told me, 'You may go along beside my servants until they have finished gathering all my harvest!'"

And he said, May the Lord give you his blessing, my daughter: even better than what you did at the first is this last kind act you have done, in not going after young men, with or without wealth.

It's true that I'm your related redeemer, but there is another related redeemer even closer than I.
