'Lightly' in the Bible

And Saul's servants spoke these words {to David privately}. But David said, "[Is] it insignificant {in your sight} to become the son-in-law of the king, [as] I am a poor and lightly esteemed man?"

And they have treated the wound of my people lightly, {saying}, 'Peace, peace,' but there is no peace.

And they have treated the wound of the daughter of my people lightly, {saying}, 'Peace, peace,' but there is no peace.

And [it was] the sound of the wings of the living creatures touching lightly {one against the other}, and the sound of the wheels beside them and [the] sound of a great earthquake.
