'Tightly' in the Bible

For this nation’s heart has grown hard,And with their ears they hardly hear,And they have [tightly] closed their eyes,Otherwise they would see with their eyes,And hear with their ears,And understand with their heart, and turn [to Me]And I would heal them [spiritually].’

"For you set aside the commandment of God, and hold tightly to the tradition of men -- the washing of pitchers and cups, and you do many other such things."

That in the good ground, these are such as in an honest and good heart, having heard the word, hold it tightly, and bring forth fruit with patience.

And he who was dead came out, with linen bands folded tightly about his hands and feet, and a cloth about his face. Jesus said to them, Make him free and let him go.

Although from the beginning He had the nature of God He did not reckon His equality with God a treasure to be tightly grasped.

Having then a great high priest, who has passed through the heavens, Jesus, the Son of God, let us hold tightly to our confession.
