I’ve seen these two sentences written in two different books:
Then the whole army advanced against the three who were laying in wait for it calmly. (Albanian Folktales and Legends by Robert Elsie)
Many times in the past we had faced attacks from our enemies, but lying in wait of the mightiest army of the world had ever known was a different matter. (The Siege by Ismaïl Kadaré translated by David Bellos)
Shouldn’t it be ‘lying in wait for’? And not ‘lying in wait of’ or ‘laying in wait for’?
