Apparently, there are at least two versions of the prayer. The version in the video is this:
ܫܠܡܠܟܝ ܡܪܝܡ ܡܠܝܬ ܛܝܒܘܬܐ
ܡܪܢ ܥܡܟܝ
ܡܒܪܟܬܐ ܐܢܬܝ ܒܢܫ̈ܐ
ܘܡܒܪܟ ܗܘ ܦܐܪܐ ܕܟܪܣܟܝ ܝܫܘܥ
ܡܪܬܝ ܡܪܝܡ ܐܡܗ ܕܐܠܗܐ
ܐܬܟܫܦܝ ܚܠܦܝܢ ܚܢܢ ܚܛܝ̈ܐ
ܗܫܐ ܘܒܫܥܬܐ ܕܡܘܬܢ
ܐܡܝܢ
There's also another version that goes like this:
ܫܠܡ ܠܟܝ ܒܬܘܠܬܐ ܡܪܝܡ ܡܠܝܬ ܛܝܒܘܬܐ
ܡܪܢ ܥܡܟܝ
ܡܒܪܟܬܐ ܐܢܬܝ ܒܢܫ̈ܐ
ܘܡܒܪܟ ܗܘ ܦܐܪܐ ܕܒܟܪܣܟܝ
ܡܪܢ ܝܫܘܥ
ܐܘ ܩܕܝܫܬܐ ܡܪܝܡ ܝܠܕܬ ܐܠܗܐ
ܨܠܝ ܚܠܦܝܢ ܚܛܝ̈ܐ
ܗܫܐ ܘܒܫܥܬ ܘܡܘܬܢ
ܐܡܝܢ
Since you wanted it in text, it will only show up in an Estrangela font if your specific font settings are set to one.
