Exodus 12:32

Also, take your flocks and your herds, just as you have requested, and leave. But bless me also.” ¹ 

Ge 27:34,38; Ex 8:28; Ex 9:28; Ex 10:26

¹ tn The form is the Piel perfect with a vav (ו) consecutive (וּבֵרַכְתֶּם, uverakhtem); coming in the sequence of imperatives this perfect tense would be volitional – probably a request rather than a command.

sn Pharaoh probably meant that they should bless him also when they were sacrificing to Yahweh in their religious festival – after all, he might reason, he did let them go (after divine judgment). To bless him would mean to invoke good gifts from God for him.
