תביאי את ההפניה הרפואית ואת ההתחייבות הכספית.

In everyday Modern Hebrew, speakers very often use the 2nd-person future form as a command or request.

• תביאי literally looks like you will bring
• but in real speech it often means bring when talking to one woman

So this sentence is completely natural in spoken Hebrew.

The more formal or textbook imperative would be:

• הביאי = bring! (to one female)

In conversation, though, תביאי is much more common.

The ending -י here marks 2nd person feminine singular.

So תביאי is used when speaking to:

• one woman
• one girl

Compare:

• תביא = to one male
• תביאי = to one female
• תביאו = to more than one person

את here is the direct object marker. It usually does not get translated into English.

Hebrew uses את before a direct object that is definite/specific, such as:

• the referral
• the financial commitment

So in:

• את ההפניה
• את ההתחייבות

the word את marks those nouns as definite direct objects of תביאי.

ואת is simply:

• ו = and
• את = the direct object marker

So:

• ואת ההתחייבות הכספית = and the financial commitment

Hebrew very commonly repeats את before each definite object in a list. That makes the structure clear and sounds natural.

Because that is the normal word order in Hebrew.

Hebrew usually says:

• noun + adjective

So:

• ההפניה הרפואית = literally the referral the-medical
• ההתחייבות הכספית = literally the commitment the-financial

This is just standard Hebrew adjective placement.

In Hebrew, if the noun is definite, the adjective must also be definite.

So:

• הפניה = a referral
• ההפניה הרפואית = the medical referral

and:

• התחייבות = a commitment
• ההתחייבות הכספית = the financial commitment

Both the noun and its adjective carry definiteness.

Because adjectives in Hebrew must agree with the nouns they describe in:

• gender
• number
• definiteness

Here both nouns are feminine singular:

• הפניה = feminine singular
• התחייבות = feminine singular

So the adjectives are also feminine singular:

• רפואית
• כספית

Because one ה is the definite article the, and the other ה is part of the noun itself.

For example:

• הפניה = referral
• ה + הפניה = ההפניה = the referral

And:

• התחייבות = commitment
• ה + התחייבות = ההתחייבות = the commitment

So the double ה is completely normal.

Yes, התחייבות is singular.

That is a very common learner question, because -ות is often a feminine plural ending, but not always. Some Hebrew nouns ending in -וּת are singular abstract nouns.

Examples:

• אחריות = responsibility
• אפשרות = possibility
• התחייבות = commitment / obligation

The plural of התחייבות is:

• התחייבויות

So in this sentence, ההתחייבות is definitely singular.

Often, yes.

While it can literally mean financial commitment/obligation, in Israeli medical or administrative contexts it can refer to a specific official payment authorization or guarantee document.

So in real-life use, it may mean something like:

• a payment guarantee
• a financial authorization
• an insurer/HMO commitment form

That kind of bureaucratic meaning is very common in Hebrew medical settings.
