'Fist' in the Bible

“If men have a quarrel and one strikes the other with a stone or with his fist, and he does not die but remains in bed,

Yet today he will halt at Nob;He shakes his fist at the mountain of the daughter of Zion, the hill of Jerusalem.

“Behold, you fast for contention and strife and to strike with a wicked fist.You do not fast like you do today to make your voice heard on high.
