'Designs' in the Bible

That all of you have made designs against me, and not one of you gave me word when my son made an agreement with the son of Jesse, and not one of you has pity for me or has made my eyes open to the fact that my servant has been moved by my son against me, as at this day?

And Saul said to him, Why have you made designs against me with the son of Jesse, giving him food and a sword and getting directions from the Lord for him, and helping him to take up arms against me, and to be on the watch to make a secret attack on me as he is doing now?

Keep here with me and have no fear; for he who has designs on my life has designs on yours: but with me you will be safe.

And it was clear to David that Saul had evil designs against him, and he said to Abiathar the priest, Come here with the ephod.
