'Slipped' in the Bible

Saul tried to pin David to the wall with the spear, but he escaped from Saul’s presence, so that Saul only stuck the spear into the wall. Then David fled and escaped that night.

The people stole into the city [of Mahanaim] that day, as people who are humiliated and ashamed steal away when they retreat in battle.

“You enlarge my steps under me,And my feet have not slipped.

My steps have held closely to Your paths;My feet have not staggered.

But as for me, my feet came close to stumbling,My steps had almost slipped.

My concern was because of the false brothers [those people masquerading as Christians] who had been secretly smuggled in [to the community of believers]. They had slipped in to spy on the freedom which we have in Christ Jesus, in order to bring us back into bondage [under the Law of Moses].
