'Stroke' in the Bible

Then Abishai said to David, “Today God has delivered your enemy into your hand; now therefore, please let me strike him with the spear to the ground with one stroke, and I will not strike him the second time.”

By oppression and judgment He was taken away;And as for His generation, who consideredThat He was cut off out of the land of the livingFor the transgression of my people, to whom the stroke was due?

For truly I say to you, until heaven and earth pass away, not the smallest letter or stroke shall pass from the Law until all is accomplished.

But it is easier for heaven and earth to pass away than for one stroke of a letter of the Law to fail.
