no one who speaks by the Spirit of God can say

"no Christian who has the Spirit of God in him can say" or "no one who is prophesying by the power of the Spirit of God can say."

Jesus is accursed

"God will punish Jesus" or "God will make Jesus suffer"

No one can say, "Jesus is Lord," except by the Holy Spirit

"One can say, 'Jesus is Lord,' only by the Holy Spirit". This sentence probably means that no one can say that Jesus is Yahweh, God in the flesh, without the Holy Spirit's influence drawing them to accept this truth. If this statement is translated poorly, it can have unintended theological consequences.

by the Holy Spirit

"with the help of the Holy Spirit" or "by the power that the Holy Spirit gives him"
