'Lovable' in the Bible

Now it is an extraordinary thing for one to willingly give his life even for an upright man, though perhaps for a good man [one who is noble and selfless and worthy] someone might even dare to die.

Finally, believers, whatever is true, whatever is honorable and worthy of respect, whatever is right and confirmed by God’s word, whatever is pure and wholesome, whatever is lovely and brings peace, whatever is admirable and of good repute; if there is any excellence, if there is anything worthy of praise, think continually on these things [center your mind on them, and implant them in your heart].
