'Though' in the Bible

He said to me, 'Please stand over me and kill me, for convulsions have seized me, even though my life [is still] in me.'

I [am] weak today even though anointed king, and these men, the sons of Zeruiah, [are] crueler than I [am]. May Yahweh pay them back for doing wickedness according to their [own] wickedness."

And Mephibosheth [was] living in Jerusalem, because he [was] continually eating at the table of the king, [even though] he [was] lame in both of his feet.

Though you did this in secret, I will do this thing before all of Israel {in broad daylight}!'"
