that they may know. God’s acts are often said to have the purpose of bringing about knowledge (Ex. 8:10; Deut. 4:35; 2 Kin. 19:19; Is. 45:6). Such knowledge is never merely intellectual. It is, however, attainable through hearing the news of God’s acts, as well as by seeing them (2:9, 10; 4:24). Here the object of knowledge is the presence of God with Joshua (1:5 note; cf. Ex. 14:31), which the people will experience through the faithfulness of God to His promises. See notes on v. 10; 4:24.
