'Stroke' in the Bible

Amasa did not notice the sword that Joab was holding in his hand. Joab stabbed him in the abdomen, spilling his intestines to the ground in a single stroke and killing him. After this, Joab and his brother pursued Bichri's son Sheba.

And every stroke of his punishing rod that the LORD brings down on them will be to the sound of tambourines and harps, as he fights against her in battle with a brandished arm.

"Son of Man, pay attention! I'm about to take away your most precious treasure with a single, fatal stroke, but you are not to mourn, weep, nor even let tears well up in your eyes.

because I tell all of you with certainty that until heaven and earth disappear, not one letter or one stroke of a letter will disappear from the Law until everything has been accomplished.

However, it is easier for heaven and earth to disappear than for one stroke of a letter in the Law to be dropped.
