'It is the Lord' in the Bible
Be certain then today that it is the Lord your God who goes over before you like an all-burning fire; he will send destruction on them, crushing them before you; and you will send them in flight, putting an end to them quickly, as the Lord has said.
"It is the LORD your God who will cross ahead of you; He will destroy these nations before you, and you shall dispossess them Joshua is the one who will cross ahead of you, just as the LORD has spoken.
Be strong, courageous, and firm; fear not nor be in terror before them, for it is the Lord your God Who goes with you; He will not fail you or forsake you.
It is the Lord Who goes before you; He will [march] with you; He will not fail you or let you go or forsake you; [let there be no cowardice or flinching, but] fear not, neither become broken [in spirit -- "depressed, dismayed, and unnerved with alarm].
