Mashiah - During Sefirah? Maybe!
gog1.com reports that Rav Mordechai Eliyahu was giving a lecture on Sefirat Ha'Omer. In the middle of the lecture, he discussed whether or not one should say that the Mitzvah of counting the Omer is based on the verse:
וּסְפַרְתֶּם לָכֶם, מִמָּחֳרַת הַשַּׁבָּת, מִיּוֹם הֲבִיאֲכֶם, אֶת-עֹמֶר הַתְּנוּפָה: שֶׁבַע שַׁבָּתוֹת, תְּמִימֹת תִּהְיֶינָה. עַד מִמָּחֳרַת הַשַּׁבָּת הַשְּׁבִיעִת, תִּסְפְּרוּ חֲמִשִּׁים יוֹם; וְהִקְרַבְתֶּם מִנְחָה חֲדָשָׁה, לַיהוָה
in the Leshaim Yihud that one recites before saying the blessing. Mentioning the verse would imply that the obligation to count nowadays is Biblical, when there is an argument, and most, in fact, hold that the obligation nowadays is only Rabbinical.
Rav Eliyahu said the following:
We are now counting the omer. We said [that the obligation is based on] an argument.
The Mashiah will come in the middle of the time period. Then, we will tell him, "What should we say for the Leshaim Yihud?"
Notice that Rav Eliyahu did not say "If" he will come, nor did he say "May it be Hashem's will" that he will come. Rather, he simply said "He will come".
Slip of the tongue or subliminal revelation?
