Here Moses is speaking as if the enemy’s oppression were a yoke of iron placed on the Israelites’ necks. This image emphasizes that the oppression will be harsh, inescapable, and degrading, like the heavy iron yoke that would be put on a work animal. Your language may have a comparable expression that you can use in your translation, or you could state the meaning plainly. Alternate translation: [And he will make you slaves under harsh and inescapable oppression]
