▼ The construction is unusual in that it says, “And Egypt will know.” The verb is plural, and so “Egypt” must mean “the Egyptians.” The verb is the perfect tense with the vav consecutive, showing that this recognition or acknowledgment by Egypt will be the result or purpose of the defeat of them by God.

▼ The form is בְּהִכָּבְדִי (b^ehikkav^edi), the Niphal infinitive construct with a preposition and a suffix. For the suffix on a Niphal, see GKC 162-63 #61.c. The word forms a temporal clause in the line.
