He shall deliver thee in six troubles: yea, in seven (comp. Amos 1:3, Amos 1:6, Amos 1:9, Amos 1:11, Amos 1:13, "For three transgressions … and for four"). An idiomatic way of expressing an indefinite number.
There shall no evil touch thee; i.e. no real evil, nothing calculated to do thee real hurt. All affliction is "for the present grievous;" but if it "afterward yieldeth the peaceable fruit of righteousness unto them that are exercised thereby" (Hebrews 12:11), it does not do us harm, but good.
