Exodus 17:15 YLT

¹³  and Joshua weakeneth Amalek and his people by the mouth of the sword.

¹⁴  And Jehovah saith unto Moses, 'Write this, a memorial in a Book, and set 'it' in the ears of Joshua, that I do utterly wipe away the remembrance of Amalek from under the heavens;'

¹⁵  and Moses buildeth an altar, and calleth its name Jehovah-Nissi,

¹⁶  and saith, 'Because a hand 'is' on the throne of Jah, war 'is' to Jehovah with Amalek from generation -- generation.'
