G4642–σκληρός–sklēros

And he who had had the one talent came and said, Lord, I had knowledge that you are a hard man, getting in grain where you have not put seed, and making profits for which you have done no work:

σκληρὸς sklēros “hard”

Then, hearing this, a number of his disciples said, This is a hard saying; who is able to take in such teaching?

σκληρός sklēros “Difficult”

And he said, Who are you, Lord? And he said, I am Jesus, whom you are attacking:

σκληρόν sklēron “hard”

And when we had all gone down on the earth, a voice came to me, saying in the Hebrew language, Saul, Saul, why are you attacking me so cruelly? It is hard for you to go against the impulse which is driving you.

σκληρόν sklēron “[It is] hard”

And again ships, though they are so great and are moved by violent winds, are turned by a very small guiding-blade, at the impulse of the man who is using it.

σκληρῶν sklērōn “strong”

To be the judge of all, and to give a decision against all those whose lives are unpleasing to him, because of the evil acts which they have done, and because of all the hard things which sinners without fear of God have said against him.

σκληρῶν sklērōn “harsh [things]”
