Discovery BoxExodus 9:5 
Context9:5 The Lord set 1 an appointed time, saying, “Tomorrow the Lord will do this 2 in the land.”
Exodus 9:18
Context9:18 I am going to cause very severe hail to rain down 3 about this time tomorrow, such hail as has never occurred 4 in Egypt from the day it was founded 5 until now.
1 tn Heb “and Yahweh set.”
2 tn Heb “this thing.”
3 tn הִנְנִי מַמְטִיר (hinÿni mamtir) is the futur instans construction, giving an imminent future translation: “Here – I am about to cause it to rain.”
4 tn Heb “which not was like it in Egypt.” The pronoun suffix serves as the resumptive pronoun for the relative particle: “which…like it” becomes “the like of which has not been.” The word “hail” is added in the translation to make clear the referent of the relative particle.
5 tn The form הִוָּסְדָה (hivvasdah) is perhaps a rare Niphal perfect and not an infinitive (U. Cassuto, Exodus, 117).
