Adonai s'fatai tiftach, ufi yagid t'hilatecha
אֲדֹנָי שְׂפָתַי תִּפְתָּח וּפִי יַגִּיד תְּהִלָּתֶךָ
O Lord, open my lips, so that my mouth may praise You.
This verse (Ps 51:17) is spoken before the Amidah.
Alexander Massey's setting includes the option of English words; also both sections can be sung as a round.
