'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.

Be strong and take heart, and have no fear of them: for it is the Lord your God who is going with you; he will not take away his help from you.

It is the Lord who goes before you; he will be with you, he will not take away his help from you or give you up: so have no fear.
