'Easy' in the Bible

"You replied and said to me, 'We have sinned against Yahweh, [and now] we will go up and fight according to all that Yahweh our God commanded us'; and [so] each man fastened on {his battle gear}, and you regarded [it] as easy to go up [into] the hill country.

Hezekiah answered, "It is easy for the shadow to lengthen ten steps. No, but let the shadow return backwards ten steps."
