בַּיָּ֤ם דַּרְכֶּ֗ךָ ושביליך [וּֽ֭שְׁבִֽילְךָ] בְּמַ֣יִם רַבִּ֑ים וְ֝עִקְּבוֹתֶ֗יךָ לֹ֣א נֹדָֽעוּ׃
Tu frayas ta route à travers la mer, ton sentier à travers des eaux épaisses: tes traces échappèrent aux regards.
Rashi on Psalms
and Your steps were not known The steps are not recognizable on the water. [The word] ועקבותיךָ means trazes in Old French, footprints.
