Rashi on Exodus 12:23/רש"י על שמות י״ב:כ״ג

1ופסח signifies AND HE WILL SPARE; and one can also explain it to mean, “and He will leap over them” (cf. Rashi on v. 13 and on Isaiah 30:5).

2ולא יתן המשחית AND HE WILL NOT GIVE THE DESTROYER He will not give him power to come in. The phrase is similar to (Genesis 31:9) “And God did not suffer him (נתנו — give him the power) to do me evil”.
