'Slip' in the Bible

He waited seven days according to the appointed time Samuel determined, but Samuel did not come to Gilgal, and {the army started to slip away from him}.

He said, 'Send me away, please, for our clan sacrifice [is] in the city, and my brother commanded me [to be present]. So then, if I have found favor in your eyes, please let me slip away and see my brothers.' Therefore he has not come to the table of the king."
