A similar theme appears in Isa 43:2 - "When you pass through the waters, I will be with you; and through the rivers, they shall not overwhelm you; when you walk through fire you shall not be burned, and the flame shall not consume you"
2 Loko wo hundza ematini,+ ndzi ta va na wena;+ ni loko wo hundza emilambyeni, a yi nge ku khukhuli.+ Loko wo famba endzilweni, a wu nge vavuriwi, ni langavi a ri nge ku hisi.+
