'Secretly' in the Bible

And Saul came to the town of Amalek, and took up his position in the valley secretly.

And Saul commanded his servants, saying, Commune with David secretly, and say, Behold, the king hath delight in thee, and all his servants love thee: now therefore be the king's son in law.

And David knew that Saul secretly practised mischief against him; and he said to Abiathar the priest, Bring hither the ephod.

Then the Ziphites came up to Gibeah to see Saul, and said, Is not David living secretly among us in the strong places in Horesh, in the hill of Hachilah to the south of the waste land

so they said to him, “Look, this is the day the Lord told you about: ‘I will hand your enemy over to you so you can do to him whatever you desire.’” Then David got up and secretly cut off the corner of Saul’s robe.

And the Ziphites came to Saul at Gibeah, and said, Is not David waiting secretly near us in the hill of Hachilah, before the waste land?
